Coding interviews test problem solving under observation. A desktop overlay can help you restate the problem and track edge cases — if you use it lightly and keep explaining your thinking out loud.
Before you code
Read the prompt twice. Say your understanding aloud. List examples, edge cases, and expected complexity target. A copilot suggestion at this stage should confirm you did not miss a constraint like empty input, duplicates, or integer overflow.
While you code
- Narrate every major decision — data structure choice, loop invariant, base case.
- Prefer small visible progress over silent perfectionism.
- Glance at the overlay for reminders; do not read long blocks verbatim.
Platform realities
Browser-based platforms may share only part of the screen. Practice once with the same microphone, speaker, and window layout you will use on interview day. Select the correct audio devices in your launch settings so interviewer speech is transcribed reliably.
After implementation
Walk through your example by hand, then mention one optimization or follow-up the interviewer might ask. Saved session transcripts help you review whether you communicated clearly or relied too heavily on hints.
