What should I do if I cannot hear the interviewer?
Say so immediately and specifically, rather than nodding through a question you did not catch. Name what failed, ask for the part you missed, and offer a workaround such as the chat box.
Say so immediately and specifically, rather than nodding through a question you did not catch. Name what failed, ask for the part you missed, and offer a workaround such as the chat box. If the problem is on your side, ask to rejoin and use the thirty seconds to switch to headphones or your backup device. Interviewers expect technical trouble and remember how calmly it was handled, not that it happened.
The same habits carry into everyday spoken English: short sentences, a clear ending, one idea at a time.
Agree on a fallback in the first minute: say that if the line drops you will rejoin within thirty seconds. Keep the recruiter's contact details from the invitation open on your phone, and type the exact question into the chat box while you ask them to repeat it, so you can answer the words they actually used rather than your reconstruction.
