under pressure?” Go deeper into the question to get more details that will
hopefully help you figure out the answer.
4. Tell the Interviewer what you do know
Most candidates commit the mistake of keeping their thoughts to themselves
when they don’t know the answer. This gives the perception that you’ve frozen
and don’t know how to proceed.
Tell the interviewer whatever little you know about the topic, and what you’re
thinking. This will help them understand that you’re trying and what’s going on
in your mind. Consequently, they’ll help you arrive at the answer by giving you
some hints (e.g. “Have you considered…”) or rephrasing the question (e.g. Let
me ask it another way…) such that it becomes easier for you to find the answer.
5. Explain Your Approach
Not all interview questions are meant to be answered completely. Sometimes,
the interviewers just want to test your thought process, ability to communicate,
and think under pressure. They want to see that you can take the initiative and
use the resources at hand to tackle new problems that you haven’t faced before.
For example, when I interviewed for Yahoo!, I was asked only one question in
my first round. The interviewer started by saying, ”None of the candidates
before you has been able to give me a complete answer to this question. So I
don’t expect you to crack it either. I just want to see how you approach the
problem and find your way out.” I was able to provide only a partial solution,
and had given up all hopes. To my surprise, I made it through to the next round.
Explain how you would go about solving the problem. You can say, "I'm not
entirely sure of an answer, but given my limited understanding of the topic, here
are a few thoughts."
While solving problems, clearly mention the parts that you don’t know, or the
assumptions you’re making. This will help you show your honesty. In fact,
many times, the interviewers will provide you the missing information and help
you shape the solution.
Similarly, during interviews, it’s common for people to make mistakes during
calculations. So you can respond by saying, “I can’t do these calculations off
the top of my head but I think they’ll give us the answer”.
