You can solve the problem. You know the data structure. But in a technical interview conducted in English, many strong Indian developers lose points not on code but on communication. Interviewers at product companies and global teams evaluate how clearly you explain your thinking, not just whether your solution compiles.

Here is how to communicate like a senior engineer, even if English is your second language.

1. Think out loud, in simple sentences

Interviewers want to hear your reasoning. Use short, clear sentences:

  • "Let me first make sure I understand the problem."
  • "My first idea is a brute-force approach. It would be O(n²)."
  • "We can improve this with a hash map. Let me explain why."

Silence for three minutes followed by perfect code scores lower than a clear walkthrough with a small bug.

2. Clarify before you code

Asking questions shows maturity:

  • "Can the input contain negative numbers?"
  • "Should I optimise for time or memory?"
  • "Is it okay if I assume the list is sorted?"

3. Use a structure for system design

Say your plan out loud before drawing anything:

  1. "First, I'll clarify requirements and scale."
  2. "Then I'll sketch the high-level architecture."
  3. "After that, I'll go deeper into the database and caching."
  4. "Finally, I'll discuss trade-offs and bottlenecks."

4. Handle "I don't know" gracefully

Never freeze. Try: "I haven't worked with that directly, but here's how I would approach it..." This keeps the conversation going and shows problem-solving.

5. Prepare your behavioural answers

"Tell me about a challenging project" and "Describe a conflict with a teammate" come up in almost every loop. Use the STAR format (Situation, Task, Action, Result) and practise each answer aloud until it takes about two minutes.

Practise speaking, not just LeetCode

Most developers practise hundreds of coding problems but never practise explaining them. Record yourself solving one problem a day while talking through it, then listen back for long pauses and filler words.
