Referred by a friend and received a response in 3 days.

The first round was a phone interview with an online code judging process. The second round was on-site, with four rounds of interviews.

The HR representatives were very nice. However, the interviewers seemed mostly busy with their work and didn't appear to have much time for the interviews. The faster you finish and the more questions you answer, the more they seemed to prefer it.

One of the interviewers asked me a lot of questions related to my previous projects, which I didn't think were relevant.

Implement a circular queue with basic queue attributes for the phone interview.

Onsite:

1. Isolated island number in a matrix.
2. Merge sort (pure merge sort), with absolutely no bugs.
3. Selling Stock III.
4. Huffman coding implementation.
