Be honest. Toot your own horn if you excelled. However, if
you did not do well, you should offer an explanation
for your grades.
If you attended a large school and did not take advantage of
the professional and social organizations there, the
interviewer may wonder why. A good reason for not being
involved in many extracurricular activities is that you carried
an unusually heavy course load or were working nearly full-time
to help finance your education.
The interviewer may want to know if your skills are
up-to-date, especially if you graduated several years ago.
Talk about on-the-job training and journal articles you've kept
up with, as well as seminars, classes, and so on.
Even if your grades were low, do not make excuses. Simply
explain the situation and tell how you would do things
differently now.
Most interviewers like to see that you helped put yourself
through school. If you did not, offer a reason.
Some students give up on courses after they discover
that real academic work will be involved. If you dropped a
course, offer a reason for it.
The interviewer is wondering how much foresight you had
when selecting the courses you would take in college.
Stress how the courses you did choose helped, and mention one
or two courses that you would like to take.
Amazingly enough, some interviewers will ask you this
question even if you're ten years out of school. If you do
not know the answer, you should be able to find out from the
registrar's office at the school you graduated from.
If you liked school, say so. If pressed to give an answer,
try not to complain or blame others.
The interviewer may want to know how much influence your
educators had upon you.
Even if you had an A average, it could have been better.
Think about what you would do if you had the chance to do
it over again.
If it was, great -- tell why. If it wasn't, do not wallow
in self-pity -- explain how you would do things
differently now.
