English in Interviews
Feedback and Tips
Based on feedback from mock interviews with natives/teachers, here are the main tips to improve your performance in English interviews:
1. The âShow, Donât Tellâ Rule
Instead of simply stating âYes, I know Node.jsâ, demonstrate your knowledge through real examples from your experience. Provide context on where and how you used the tool (e.g., âI used Node.js to build a serverless architectureâŠâ). The interviewer evaluates your technical proficiency much better when you tell a story associated with the technology.
2. Control âHesitation Markersâ
It is normal to hesitate and look for words, but doing it too much harms communication fluency.
- What to avoid: Elongating vowel sounds (e.g., âsooooâŠâ, âand aaaaâŠâ) or using filler words (âlikeâ, âyou knowâ).
- What to do: Replace these hesitations with silence. A half-second to one-second pause sounds natural, shows confidence, and gives your brain time to formulate the sentence correctly.
3. Important Grammar Points
- Tools donât have gender: When talking about AI (ChatGPT, Copilot, NotebookLM), never use him or her. Always use it.
- Simple Present for Routines: When describing continuous processes in your current job, use the simple present (âI use this AI agentâ, âI write specsâ) and avoid unnecessary gerunds (âIâm usingâ, âI like to developingâ).
- Relative Clauses: Use where or which/that for environments (e.g., âenvironments where I can createâŠâ), never use who, as it is reserved only for people.
- Regular Plurals and Articles: Words like people and children are already plural. Do not say âa different peopleâ. Just say âdifferent peopleâ or âsome different peopleâ.
4. Technical Vocabulary â Pronunciation and Usage Pitfalls
Feedback from the mock with Augusto Bretas (English coach, 7/7/2026):
- Harness, not âharmlessâ or âharmonyâ: When talking about AI guardrails, the correct word is harness (or guardrails). âWe set up guardrails so the AI doesnât commit code directly.â
- Harnesses (plural) works equally: âThe harnesses Iâve built prevent hallucinations from reaching production.â
- Donât use him/her for AI tools â repeated because itâs a very common mistake. âNotebookLM is great for discovery â it ingests documentation and helps me map dependencies.â (not: âhe reads the docsâ)
5. Rhythm and Fluency â What Works Well
Augustoâs feedback was mostly positive with specific refinement points:
What you do well:
- Illustrating answers with examples: When asked about Node.js, you brought a real project. When asked about CI/CD, you brought a concrete example. This âShow, Donât Tellâ pattern is highly valued.
- Pacing: Speed and clarity were appropriate for interviewers who donât have English as their first language.
What to improve:
- Hesitation markers (see section 2): the level was acceptable but can improve with practice.
- Verb tense for routines: use the simple present, not the gerund, to describe habitual workflows.
Context: Sphise Interview (ended due to fluency)
In the interview with Sphise (7/3/2026, 9 minutes), the process was terminated early because the position required fluent English (C1/native level) for integration with a mostly American team.
Lesson: When a role specifies fluent English as a requirement, clarify in the initial screening whether your B2 level is sufficient â it avoids awkwardness and saves time for both sides. That said, the interviewer appreciated the honesty in declaring your actual level.
