Advice from candidates

14 pieces of advice, in their own words. Names removed.

• you might have many interviews on the same day. One of them might not have gone well. The interviewer would have given negative feedback, but don't let that ruin your other interview.

• I found lacking knowledge of what to do is the biggest problem I faced during internship preparation. So, for placements I started early and contacted some seniors and peers how they prepared. This time I gained knowledge, and solved almost the entire striver sheet during summer. I gave some leetcode contests and mock online tests for time management. Yeah this is what I have done practice.. practice.. practice..

• you might think once I enter the college in August, i will start preparing for placements. I recommend starting early is a good option.

• I think all the company wants from a candidate is that whether he has the ability to think deeply in the problem or atleast try. All they want us to know is our thoughts towards approaching the probelm. One has to think aloud in the interview.
