2026 Goldman Sachs Coding Interview Real Questions & Solutions

programhelp-cs — Fri, 17 Apr 2026 06:59:41 +0000

Hi everyone, I recently completed the 2026 Goldman Sachs Coding Interview. The interview mainly focuses on real coding ability, data structure design, and problem-solving under pressure. This article shares the actual questions I encountered along with detailed explanations and Python solutions.

Goldman Sachs interviews are typically LeetCode Medium level, sometimes involving design problems or business-style scenarios. Interviewers pay close attention to communication, edge cases, and code readability.

Problem 1: Transaction Segments

Problem Summary:
Given an array of transaction amounts and an integer k, count how many contiguous subarrays of length exactly k are strictly increasing.

Key Idea:
Use a sliding window or linear scan to check each subarray of size k and verify strict increasing order.

Problem 2: Efficient Tasks

Problem Summary:
Assign modules to 3 servers under constraints, and maximize the minimum value among all assignments.

Key Idea:
This is a classic “maximize the minimum” problem, typically solved using binary search combined with greedy validation or dynamic programming.

Problem 3: Design HashMap

Problem Statement:
Design a HashMap without using built-in hash table libraries. Implement the following operations:

MyHashMap() - initialize the data structure
put(key, value) - insert or update a key-value pair
get(key) - return value or -1 if not found
remove(key) - delete key if exists

Solution Idea

We use chaining to handle collisions. The structure contains a fixed-size bucket array, where each bucket stores key-value pairs.

Hash function: key % bucket_size
Collision handling: list-based chaining
Operations: linear search within each bucket

Python Implementation

class MyHashMap:

    def __init__(self):
        self.bucket_count = 10007
        self.hash_map = [[] for _ in range(self.bucket_count)]

    def _hash(self, key: int) -> int:
        return key % self.bucket_count

    def put(self, key: int, value: int) -> None:
        index = self._hash(key)
        for i, (k, v) in enumerate(self.hash_map[index]):
            if k == key:
                self.hash_map[index][i] = (key, value)
                return
        self.hash_map[index].append((key, value))

    def get(self, key: int) -> int:
        index = self._hash(key)
        for k, v in self.hash_map[index]:
            if k == key:
                return v
        return -1

    def remove(self, key: int) -> None:
        index = self._hash(key)
        for i, (k, v) in enumerate(self.hash_map[index]):
            if k == key:
                del self.hash_map[index][i]
                return

Complexity

Average Time: O(1)
Worst Case: O(n)
Space: O(n)

Interview Tips

Focus on explaining edge cases clearly
Communicate while coding
Expect follow-ups on rehashing and load factor
Practice LeetCode Medium problems (Array, DP, Greedy, Design)

Good luck with your Goldman Sachs interview preparation!

Microsoft OA High-Frequency Questions 2026

programhelp-cs — Fri, 10 Apr 2026 07:05:48 +0000

Recently completed the Microsoft 2026 SDE Online Assessment (New Grad + Intern). One-line summary: Stable structure, but increasing difficulty and time pressure.

Platforms are mainly HackerRank or Codility, with a typical format:

2 questions
75–90 minutes (Codility sometimes 110 minutes)

Questions are mostly Medium, occasionally Medium-Hard, with stronger emphasis on:

Engineering thinking
Edge case handling
Code robustness

1. Stacks / Blocks Conversion

Description:

Given an array where each number represents a stack of blocks. Every 2 blocks can merge into 1 and carry to the next stack. Repeat until no more merges are possible. Return remaining single blocks.

Example: [5,3,1]

Key Idea:

Simulate from left to right
Carry-over like binary addition (base-2 behavior)
Use long for large values (up to 1e9)

Pitfalls:

All 1s or all 0s
Overflow issues
Empty input

2. Circular Character Roll

Description:

Given a string s and an array roll, for each roll[i], increment the first roll[i] characters cyclically. ('z' → 'a')

Optimized Approach:

Avoid brute force
Use difference array + prefix sum
Apply total shifts once (mod 26)

Why Important:

Classic 2026 high-frequency pattern testing string optimization.

3. Subarray Permutation Check

Description:

Given a permutation of 1..N, check if there exists a subarray of length K that forms a valid permutation.

Key Idea:

Sliding window
Track max + uniqueness
Condition: max == K and no duplicates

Optimization: O(N) required — brute force will TLE.

4. String Without 3 Consecutive Letters

Description:

Given a string of 'a' and 'b', remove minimum characters to avoid 'aaa' or 'bbb'.

Approach:

Greedy traversal
Track consecutive count
Delete when count exceeds 2

Variants:

Lexicographically smallest string problems

5. Other High-Frequency Topics (2026)

Graph: Connected components (Union-Find / DFS)
DP: Stock trading, House Robber, Jump Game VI
Sliding Window: Subarray optimization
Greedy: Load balancing / task allocation
BFS: Shortest path / escape problems

Microsoft OA 2026 Strategy

IBM OA High-Frequency Questions Sharing | How to Pass IBM OA Efficiently

programhelp-cs — Sun, 05 Apr 2026 15:17:36 +0000

I recently completed the Online Assessment (OA) for IBM, and the overall experience was quite smooth. Compared to other big tech companies, IBM’s coding questions tend to be more foundational. As long as you maintain consistent practice on LeetCode and are familiar with common algorithm templates, passing the OA is usually very achievable.

At the same time, I’ve been preparing for OA and VO rounds from companies like Amazon, Google, and Microsoft. Based on this experience, I’ve compiled and summarized several high-frequency IBM OA questions to help those who are currently preparing.

1. IBM OA Overview

Typically 2 coding questions
Relatively flexible time constraints
Focus on fundamental algorithms and data structures
Requires clean code and solid edge case handling

2. High-Frequency Questions

Question 1: High Load Timestamp Index

Description: Given an array load[] representing server load, return all indices i (0-based) where load[i] > 2 × average load. Return the indices in ascending order. If none exist, return an empty array.

Constraints: 1 ≤ n ≤ 2×10^5, 1 ≤ load[i] ≤ 10^9
Key Points: Array traversal, average calculation, precision handling

Question 2: Minimum Total Cost of Items

Description: There are numItems items, each with multiple pricing options given by itemId[] and cost[]. Choose one price per item such that the total cost is minimized. If any item has no available price, return -1.

Example: Minimum costs for items 0, 1, 2 are 7, 6, and 8 respectively, total cost = 21.
Key Points: Grouping + minimum value selection using hashmap or array

Question 3: Maximum Non-Overlapping Intervals

Description: Given n intervals [startTime[i], endTime[i]), find the maximum number of non-overlapping intervals.

Constraints: n ≤ 10^5
Key Points: Classic greedy algorithm (sort by end time and select greedily)

Question 4: Maximum Water Level Increase

Description: Given an array arr representing water levels, find the maximum difference arr[j] - arr[i] such that i < j and arr[i] < arr[j]. If no such pair exists, return -1.

Constraints: Up to 2×10^6 elements
Key Points: Single pass with tracking minimum value

3. Preparation Tips

SIG 2026 Quant / Susquehanna OA Full Guide

programhelp-cs — Fri, 03 Apr 2026 07:59:36 +0000

We've compiled a comprehensive overview of SIG 2026 Quant and Susquehanna OA. This guide covers Online Assessment (OA), Quant Assessment, and Phone Interview question types, giving you insight into what to expect and how to prepare. The core focus is probability reasoning, decision-making, and fast computation skills.

OA Question Types

The OA mainly tests mathematics, probability, and decision-making. There aren't too many questions, but each one emphasizes logical clarity and model fluency.

Random Events & Probability

Two trips last year, one in December—what is the probability both are international?
Randomly select three points on a unit circle—what is the probability of forming an obtuse triangle?
Pick 3 numbers from 1–20—what is the probability that one equals the average of the other two?
Three independent U[0,3] random variables—probability that the median falls in [1,2].

Random Processes & Expectation

Alternate rolling dice A and B until A rolls a 6—compute probability game ends at A’s turn and expected number of rolls.
Bus waiting time problem: Route A U(0,10), Route B U(0,20)—calculate expected waiting time.
Ball drawing problem: Add a blue ball after each draw, compute expected draws until all balls are blue.
Cube cutting problem: Cube painted blue, sliced horizontally and vertically twice—probability a random cube has the original color on top.
Biased coin with probability p, rolled 16 times—expected number of consecutive heads.

Strategy & Decision Making

Penney's Game: Player 1 picks HHT, Player 2 picks HTH—who has the advantage and winning probabilities?
Poker blind raise: Friend raises to $20, what is the minimum win probability to call?
Decision making with risk: Prize options of $1,000, $4,000, $250—calculate minimum correct probability.

Combinatorics & Counting

Eight-person round table: three random seats—probability at least two are adjacent / probability all are non-adjacent.
n lines cutting a circle—maximum number of regions possible.
Random chord on a unit circle—expected length.

Phone Interview Questions

Beyond the OA, SIG’s phone interview covers both Behavioral and quantitative reasoning:

Why did you choose Quant Research?
Are you interviewing for other QR or trading roles?
Describe your research experience.
Why SIG?
Expected graduation and post-graduation plans (technical / academic / finance)?

Stripe SDE Interview – 5 Rounds VO Recap | Easy Coding, Hard System Design Details

programhelp-cs — Fri, 27 Feb 2026 14:49:48 +0000

I recently completed the five-round Virtual Onsite (VO) interview with Stripe, and wanted to share a detailed breakdown while everything is still fresh. Overall difficulty: medium. Stripe does not focus on tricky algorithms, but places extremely high standards on engineering quality, financial system understanding, and clean, production-ready thinking.

Interviewers were friendly and professional. No pressure-style questioning. Instead, they evaluate:

Clarity of thinking
Code robustness
Production-level design decisions
Ability to reason about financial systems

Round 1: Coding — Account Balance Settlement

Problem: Given current balances and target balances for a group of accounts, construct transactions to settle all accounts to their target values.

This is similar to the “minimum transaction” modeling problem, but you only need to generate a valid solution — optimality is NOT required.

Approach

Compute net difference (target - current)
Separate positive and negative balances
Use two pointers or queues to match payers and receivers
Generate transaction records
Handle edge cases (already balanced, empty input, single account, etc.)

Follow-ups

Minimum number of transactions? Explain DFS / backtracking with pruning logic. No need to fully implement, but reasoning must be complete.
How to design an Audit mechanism? Financial-system mindset is key:
- Dry run all transactions in memory
- Generate theoretical ledger state
- Compare against DB records
- Output discrepancies

Round 2: Hiring Manager Chat

Very conversational and technical-depth focused.

Deep dive into past projects
Technology choices and trade-offs
Ownership and cross-team collaboration
Conflict handling

This round evaluates communication clarity, engineering maturity, and team fit more than algorithm skill.

Round 3: API Integration

Pure engineering fundamentals — no algorithm tricks.

Clone a repo
Call a given API
Process response
Persist data
Handle errors properly

Difficulty is low. The real test is whether your code:

Runs end-to-end
Is structured cleanly
Handles edge cases
Shows production-level habits

Round 4: Debug (Mako Debugging)

Very production-realistic debugging session.

Given unfamiliar Mako-related code, identify and fix bugs such as:

File path not validated as directory
Missing AST node visitor leading to runtime crash

Key evaluation points:

Reading unfamiliar code quickly
Tracing call stacks
Understanding dependencies
Providing practical, production-ready fixes

Round 5: System Design — Ledger Service

This is the most important round at Stripe.

Do NOT use generic system design templates.

Design a production-grade Ledger Service with financial-level rigor.

Critical Details Interviewers Care About:

API design (request/response modeling)
Transaction ID strategy
Idempotency guarantees
Strong consistency model
Concurrency control
Duplicate submission prevention
Audit trail design
Database schema
Double-entry accounting model

If you only discuss load balancers, caching, and layered architecture, you will quickly get pushed into detail-level failure. Stripe expects designs that could go to production tomorrow.

Final Thoughts

Stripe VO moves fast and emphasizes engineering depth:

Coding is straightforward but must be stable and edge-complete
Debug/API rounds test real-world development ability
System Design focuses on financial-level correctness

Interview success is rarely about talent. It is about preparation density.

Stripe / Big Tech SDE Interview Support

We provide structured preparation for North America top-tier tech companies, covering:

Coding simulations
Debug rounds
API integration practice
Fintech-level system design

Full-process mock interviews and real-time interview shadowing support to help you stabilize every round of your VO.

If you are preparing for Stripe, Fintech, FAANG or other SDE roles, don’t gamble your interviews on last-minute performance. Strategic preparation always outperforms blind LeetCode grinding.

Microsoft OA Medium-Level Problem Breakdown | Session Token Design + String Manipulation

programhelp-cs — Thu, 26 Feb 2026 15:28:03 +0000

Recently, big tech OAs have clearly entered peak season. Companies like Google, TikTok, and Amazon are rolling out assessments back-to-back. I just completed this Microsoft OA set — overall difficulty felt medium to upper-medium. It’s not template-based, but also not trick-heavy. The core evaluation focuses on data structure fundamentals and implementation stability under time pressure.

Q1: Maximum String Operations (String Manipulation)

Problem Summary

You can choose three consecutive characters s[i], s[i+1], s[i+2]. If the first two characters are equal and the third character is different, you may change the third character to match the first two. Return the maximum number of operations possible.

Core Insight

The key idea is propagation. Once a contiguous block of identical characters has length ≥ 2, it can spread to the right and convert different characters one by one.

Optimal Strategy (O(n))

Traverse from left to right.
Track the current consecutive identical character length.
If the streak ≥ 2 and the next character differs, count one operation and extend the streak.
No need to actually modify the string.

You only need to count how many characters can be absorbed by a valid streak. If string length < 3, return 0.

Q2: Session Authentication System (Token Design)

Problem Summary

Design a token authentication system with expiration rules. Each token has expiration time = current_time + TTL.

generate(token_id, current_time)
renew(token_id, current_time)
count(current_time)

Before any operation, expired tokens must be removed. If expire_time ≤ current_time, it is considered expired. Expired tokens cannot be renewed and must not be counted.

Clean Design

Use a HashMap:

token_id → expire_time

Operation Logic

Cleanup Step (Before Every Operation)

Remove tokens where expire_time ≤ current_time

generate

expire_time = current_time + TTL
store in hashmap

renew

If token exists and not expired, update expire_time

count

Cleanup first
Return hashmap size

Common mistake: using < instead of ≤ in expiration check. Also avoid overengineering with heaps or ordered sets. HashMap is sufficient for OA scope.

Practical Advice for Big Tech OA Preparation

Across Microsoft, Google, TikTok, and Amazon, the trend is clear: it’s not about just solving — it’s about stable AC under pressure.

Master boundary conditions (index bounds, expiration edges, empty inputs)
Train under time constraints (target: 2 problems AC within 30 minutes)
Keep code structure clean and readable
Think before coding — avoid brute-force traps

Many candidates don’t fail due to lack of ability. They lose points due to unstable execution under real exam pressure.

Need Practical Support?

If you're preparing for Microsoft, Google, TikTok, or Amazon OAs and:

Want recent real problem patterns
Need high-intensity timed simulations
Keep getting stuck on string/design/DP/graph problems
Want structured strategy guidance

You can reach out for practical interview assistance to improve both your problem-solving rhythm and pass rate.

Stability wins OAs.

26NG IBM OA Experience | HackerRank 2 Coding Questions + AC Tips

programhelp-cs — Fri, 20 Feb 2026 14:12:37 +0000

I just completed the 26NG OA for IBM on HackerRank, and overall the experience can be summarized in two words: stable and standard. The format was very typical — two coding questions with sufficient time provided. The problems were not tricky, mainly focused on common data structure and algorithm applications. However, getting AC in one go still requires solid fundamentals and careful boundary handling.

26NG IBM OA Question 1

Problem: For each query, compute the total number of possible square subgrids in a grid.

Key Idea:

The number of squares with side length a is: (r - a + 1) * (c - a + 1)
a ranges from 1 to min(r, c)
Instead of brute force enumeration, simplify using summation formulas
The final result can be computed in O(1)

This is a pure math simplification problem. No need to enumerate each square size explicitly. Just be careful with integer overflow — use long instead of int if constraints are large.

26NG IBM OA Question 2

Problem: Given a binary string (containing only '0' and '1'), determine whether it can become a palindrome and compute the minimum number of swaps required.

Step 1 — Feasibility Check:

Let n be the string length
Let count1 be the number of '1's
If n is even → count1 must be even
If n is odd → count1 must be odd

If the parity condition fails, forming a palindrome is impossible.

Step 2 — Minimum Swaps:

Traverse the first half of the string
Compare s[i] with s[n - 1 - i]
Count mismatched pairs
Answer = mismatched_pairs / 2

The implementation is short and clean. The key is validating feasibility before calculating swaps.

Overall Takeaways

The IBM 26NG OA is not extremely difficult, but stable execution matters. Many candidates don’t fail because they don’t know the solution — they fail because of:

Boundary condition mistakes
Small implementation bugs
Wasting time debugging during the test
Careless overflow issues

If you’re preparing for IBM or other major tech company OAs like Amazon, Meta, or TikTok on platforms such as HackerRank or CodeSignal, getting familiar with real question patterns and pacing is critical.

Latest BCG DS OA — Passed in 60 Minutes (Full Breakdown)

programhelp-cs — Wed, 18 Feb 2026 14:59:40 +0000

I just completed the BCG DS OA today — 60 minutes, 4 questions, all heavily focused on practical data analysis and machine learning workflows.

The overall difficulty wasn’t extreme, but it was very engineering-oriented. This felt aligned with the working style of BCG X — structured, practical, and focused on real-world execution rather than algorithm tricks.

I used Python throughout (mainly pandas + sklearn). If you're comfortable with data cleaning, feature engineering, and model evaluation pipelines, the timing is manageable.

Question 1: Aggregation + Multi-Table Integration

The first question focused on aggregation and summary metrics. You need to read the driver dataset, compute the average rating, count drivers who speak a second language, calculate their proportion among all drivers, and then merge trip data to compute the successful completion rate.

The final step is to combine all metrics and export them into a CSV file. The challenge is not complexity but precision — ensuring correct denominators, proper grouping logic, and clean output formatting.

Question 2: Proper ML Preprocessing Pipeline

This section tests machine learning workflow discipline. You must load training and testing datasets, fill missing age values using the rounded mean from the training set, and encode categorical variables such as car model and second language.

Mappings must be built strictly from the training set and then applied to the test set to avoid data leakage. Tip amounts require standardization, driver grades (A/B) must be converted to binary values, and outputs must preserve five decimal places before saving to a new file.

This question evaluates whether you understand clean separation between training and testing processes.

Question 3: Multi-Table Joins + Business Feature Engineering

This question resembles real DS work. You must read driver, vehicle, and trip datasets, calculate days since last vehicle inspection, join data via car_id, and compute driving experience (2023 minus start year).

You also aggregate total likes received per driver across multiple dimensions and ensure drivers without trips receive zero likes. After standardizing column names and selecting required fields, you output the final dataset to collected.csv.

This part tests merge accuracy, datetime handling, and structured feature construction.

Question 4: Model Training + Class Imbalance + Threshold Tuning

The final question requires loading train, validation, and test datasets, splitting features and labels, and completing a full modeling pipeline.

Numerical features require median imputation and standard scaling. Categorical features require mode imputation and label encoding. A Random Forest model is trained with higher weight assigned to class B (label 1).

You then tune classification thresholds (0.3, 0.4, etc.) on the validation set, selecting the one that achieves precision above 0.8 while maintaining reasonable recall. The optimal threshold is applied to the test set for final predictions.

Overall Impression

This OA is not algorithm-heavy. It emphasizes structured data workflows, proper ML discipline, and production-oriented thinking.

If you’re preparing for BCG X or other North American DS roles and want structured guidance on similar OAs, you can reach out to Programhelp. Having experienced support to refine your workflow and avoid common pitfalls can significantly improve efficiency and confidence under time pressure.

DoorDash 26NG Interview Experience | Real Questions & Answers from a Recent Candidate

programhelp-cs — Mon, 16 Feb 2026 12:16:23 +0000

Applying for DoorDash internships in 2026 feels extremely competitive. Many of my friends apply to over a dozen companies at the same time, and only the strongest candidates get interviews: usually 200+ LeetCode problems, basic system design knowledge, and the ability to talk about business logic clearly.

When I received my interview invite, I was excited but knew the difficulty would be high. Below is a full breakdown of every round, follow-up questions, and how I approached them — for anyone preparing for DoorDash 2026 NG.

Round 1: Coding — Find the Nearest Restaurant

The interviewer opened with:

“If you were a dasher starting from this location… how fast can you find the closest restaurant?”

It was a grid-based problem:

0 = path
X = wall
R = restaurant
S = starting position

I immediately used BFS. Halfway through, the interviewer asked:

Why BFS instead of DFS?

I explained BFS guarantees the shortest path in an unweighted grid, which aligns with real DoorDash routing logic.

Round 2: Coding + Dasher Dispatch Logic

I was given two lists:

Orders: location + prep time
Dashers: location + availability

“How do you assign dashers to minimize delivery time?”

The interviewer emphasized:

“We don’t need optimal. We need fast and scalable.”

I proposed three practical solutions:

Greedy assignment: nearest idle dasher
Weighted scoring: distance + prep time + rating
Zone-based matching for performance

He confirmed this was close to their real dispatch system.

Round 3: System Design — Real-Time Dasher Tracking

“Your dasher updates GPS every 3 seconds. Show me how to build real-time tracking.”

My structure:

WebSocket for real-time push
Redis for latest location only
Throttling & debouncing
Sharding by region
Pub/sub for high-scale fan-out

Round 4: System Design — Order Placement & Idempotency

“User taps order twice due to bad network. We get two payments. What do you do?”

Core solution: idempotency

Unique requestId per order
Duplicate check on backend
Atomicity between order & payment
Rollback on payment failure

Round 5: Behavioral Questions

DoorDash focuses on real stories, not generic answers:

Why DoorDash? — Show interest in real-time logistics & mapping
Conflict in collaboration? — Use prototypes & data to decide
Fast-paced environment? — Stay organized with checklists & docs

Final Takeaways

DoorDash does not test hard-to-solve problems or fancy architectures. They test whether you can:

Break down problems quickly
Make real-world tradeoffs
Understand logistics & real-time systems
Start contributing immediately

For system design and behavioral prep, I worked with Programhelp for VO mock interviews. Their feedback helped me answer follow-ups naturally and think like a real engineer.

For Those Going for DoorDash 26NG

If you’ve reached the VO stage, you’re very close to an offer. But DoorDash’s system design and coding pace can be tough for NGs.
