First, I was contacted by the recruiter, and we set up a time for the phone screen interview. I did well on the phone screen interview and was asked to pick a time for on-site interviews.

However, after a holiday break, I received an email from the recruiter saying they had completed hiring. This was quite surprising to me because when I had my first conversation with the recruiter, I explicitly asked about the hiring window and headcount, and the recruiter told me there was no need to worry about the headcount.

Definitely not a good experience.

Based on what I heard, there is indeed a hiring window for new grads. They started hiring in September, and by December, they are almost done. So don't wait until it's too late.

To prepare, read through the interview questions on Glassdoor, and you'll be fine.

Recruiter: Why LinkedIn?

Phone:

1. Your research/project. Basic knowledge like thread vs process, object class.
2. Convert a tree to its mirror.
3. Implement a hash table and make it thread-safe.
