Department Structure:
Performance Review Schedule:
- Trainee: Performance review every 3 months.
- Junior 1, Junior 2, Junior 3: Performance review every 3 months.
- Middle 1, Middle 2, Middle 3: Performance review every 6 months.
- Senior 1, Senior 2: Performance review every 6 months.
Note: The performance review schedule may vary depending on the specific
company's policies and guidelines.
List of topics that a developer needs to know in order to pass a performance review.
| Junior | Middle | Senior | |
|---|---|---|---|

| Code Integration | uses git to move code around | has an opinion about GitFlow | has ideas how to build a CI process and automate chores |
| Paradigms | got the idea of OOP | got hands dirty with FRP | brings value from other platforms and paradigms |
| Dependencies | knows how to use Cocoapods | knows why apps can't use SPM, but Carthage is an option | knows why it is essential to own/reduce dependencies |

| Reference | uses StackOverflow as a single source of truth | often uses official documentation | asks platform developers and can reverse engineer |
| Memory | knows how to avoid and fix a memory leak | knows NSPointerArray and why structs increase binary size | has a strategy to reduce out-of-memory crashes |
| UI | can build basic UI in the Interface Builder | has reasons to make UI in code | can take layout and diff calculation to non-main thread |

| Design Patterns | understands Delegation, Target-Action and MVC idea | is proficient at Observer, Facade and Mediator patterns | knows the sweet spot between dependency injection and service locator |
| Product Quality | the app is tested if it works on my phone | writes unit tests and tried TDD and UI tests | defines a maintainable test pyramid with non-overlapping coverage areas |
The average time to complete a task or answer a question is 10 to 15 minutes.
The average time to complete a performance review is 2-3 hours.
There are 13 sections in total. One task is provided for the solution (out of 5
in the section) at the choice of the interviewer. It is possible to provide a
second chance (the second task out of 5) if the first one causes difficulty,
with a score adjustment by a factor of ~ 0.5.

I have a clear focus on time-to-market and don't prioritize technical debt. And I took part in the Pre-Sale/RFX activity as a System Architect, assessment efforts for Mobile (iOS-Swift, Android-Kotlin), Frontend (React-TypeScript) and Backend (NodeJS-.NET-PHP-Kafka-SQL-NoSQL). And I also formed the work of Pre-Sale as a CTO from Opportunity to Proposal via knowledge transfer to Successful Delivery.
