TCS Interview
Facing the technical interview of a company is an uphill
task. It all depends on the mood of the interviewer and to an
extent on your appearance. If he is in a bad mood, the
interview can be really tough. Otherwise you might have a
slight consideration. Be prepared for any questions from every
section of your skill set. If the interviewer goes to a part
of your skill, which you are not comfortable with, try to
divert his attention to some other part in which you are an
expert. Try to explain things in a simple way and be precise
in your answers. If you don't know an answer admit it. DO NOT
try to make up and answer. That might lessen your chances of
getting through.
Here are some of the FAQ's that can be
asked in the technical interview
