I'm a Brazilian software engineer. I've been applying to international tech jobs for months. My technical skills? Solid — I can build full-stack apps, work with AWS, Docker, CI/CD, the whole stack.
My English in interviews? Disaster.
Not because I can't speak English. I can read docs, write code comments, even chat on Slack. But the moment someone asks me "Tell me about a time you dealt with a difficult stakeholder" on a video call, my brain goes blank. I start with "So, I, I'm working on a team, this team developing a system, and me too, the system is, uh, for a medical company..."
Sound familiar?
The Real Problem Isn't Your English
Here's what I learned after bombing several interviews: the problem isn't vocabulary or grammar. Most developers have enough English for that. The problem is structured verbal communication under pressure.
In your native language, you naturally organize your thoughts: setup, problem, action, result. In English, you panic and dump everything at once — jumping between past and present tense, losing track of your point, filling silence with "uh" and "like" and "you know."
Interviewers notice. Not because your English is bad, but because your answer is unstructured, and that makes you seem unprepared.
What Didn't Work
Reading interview prep articles — I read dozens of "Top 50 Behavioral Questions" posts. Useless for the actual speaking part. Knowing the STAR method intellectually doesn't help when you're nervous and speaking in real-time.
Practicing in my head — I'd think through answers while commuting. The problem? Thinking and speaking are completely different skills. Your internal monologue doesn't have filler words, hesitations, or grammar mistakes. Speaking out loud does.
ChatGPT conversations — I tried using ChatGPT as a mock interviewer. It helped with content, but it couldn't tell me that I said "uh" 23 times in a 90-second answer, or that my fluency drops when I'm explaining technical concepts.
What Actually Worked
1. Record yourself. Then listen back.
This was painful but transformative. I started recording myself answering interview questions out loud. Then I'd listen back.
The first time I did this, I was shocked. I had no idea I:
- Started every answer with "So, basically..."
- Used "uh" as a comma between every clause
- Switched between past and present tense randomly
- Never actually finished my stories — I'd trail off with "so yeah, that was it"
You can't fix what you can't see. Recording yourself is the mirror.
2. Practice the same question multiple times
Not different questions every day. The same question, 3-4 times over a week. Each time, you get a little tighter, a little more structured. By the fourth time, the answer flows naturally.
This is how native speakers prepare too — they don't improvise in interviews. They have practiced, polished answers ready to go.
3. Focus on structure, not perfection
The STAR method (Situation, Task, Action, Result) sounds basic, but forcing yourself to follow it out loud changes everything. Even if your grammar isn't perfect, a structured answer sounds 10x more competent than a rambling one.
Bad: "So I was working on this project and there were problems with the other team and I didn't know what to do and then I talked to someone and it got better."
Better: "I was assigned to integrate our API with a partner team's service. The challenge was that we had misaligned requirements — they expected REST, we'd built GraphQL. I scheduled a meeting with both tech leads, we documented the gaps, and agreed on a REST wrapper. We delivered on time and the integration handled 10K requests per day."
Same story. Same English level. Completely different impression.
4. Get objective feedback on your speaking
This is the gap I couldn't fill with existing tools. I needed someone (or something) to tell me: "Your fluency is a 4/10. You used 23 filler words. Your structure is weak — you never stated the result. Here's how your answer could sound better."
I looked for tools that did this and couldn't find exactly what I needed. So I built one.
Building My Own Solution
I'm a developer, so I did what developers do — I built a tool to solve my own problem.
FluentInterview is what came out of it. The idea is simple:
- Pick a real interview question (behavioral, technical, situational)
- Record your spoken answer (just like in a real interview)
- AI analyzes your response across 6 dimensions: fluency, vocabulary, structure, grammar, confidence, and filler word usage
- You get a detailed score, specific feedback on what to improve, and a suggested better version of your answer
The part that helped me most was seeing my filler word count and fluency score change over time. In my first recording, I scored a 3.0 on fluency (A2 level). After two weeks of daily practice, I could see the numbers moving up.
It also has a Live Interview mode where you have an actual real-time conversation with an AI interviewer — it listens to your answer, asks follow-up questions, pushes back on vague answers. That's the closest thing to a real interview I've found without actually being in one.
Practical Tips That Made a Difference
Beyond the tool, here are specific things that helped:
Watch tech content from non-American speakers. Indian tech YouTubers like TechWorld with Nana and Kunal Kushwaha helped me get used to different accents. In real interviews, your interviewer might not have a standard American accent.
Prepare 5-7 stories, not 50. Most behavioral questions map to a small set of experiences: a conflict, a failure, a leadership moment, a technical challenge, a deadline. Prepare 5-7 solid stories and learn to adapt them to different questions.
Practice your introduction until it's automatic. "Tell me about yourself" is the first question in every interview. If you nail this, your confidence carries through the rest. If you stumble here, you're playing catch-up.
Time your answers. Behavioral answers should be 60-90 seconds. Technical explanations should be 2-3 minutes max. Practice with a timer. Most non-native speakers either rush through in 30 seconds or ramble for 5 minutes.
Say "Let me think about that for a moment" instead of filling silence with "uh." This one trick made the biggest difference. A 3-second pause sounds confident. Three seconds of "uh, um, like, you know" sounds unprepared.
Where I Am Now
I'm still on this journey. My English isn't perfect and probably never will be. But my interview performance has improved dramatically since I started practicing deliberately instead of just "hoping it'll be fine."
The key insight: interview English is a specific skill, separate from general English. You can be fluent in casual conversation and still bomb an interview. It needs targeted practice.
If you're a non-native speaker preparing for international tech interviews, my advice is: start recording yourself today. Listen back. Cringe. Then do it again. The gap between where you are and where you need to be is smaller than you think — you just need the reps.
I built FluentInterview to solve this problem for myself. It's free to start if you want to try it. But honestly, even if you just record yourself on your phone and listen back, you'll see improvement. The important thing is to practice out loud, not just in your head.
If you're on the same journey, I'd love to hear what's working for you. Drop a comment or reach out — we're all figuring this out together.
