I went through two stages:

• An online assessment round
• A first interview

The online assessment consisted of two LeetCode medium-hard (mostly hard) questions. Luckily, I was able to finish the questions with an acceptable number of passing test cases. I heard back about the first round of interviews in a week, and the interview questions were pretty difficult.

One of the questions was about the Huffman encoding algorithm, which I was not able to recall correctly. When the interviewer presented the question, I was able to offer an alternate solution. However, the interviewer was fixated on me coming up with the Huffman encoding solution.

They eventually gave me a hint that I was supposed to use the Huffman algorithm, but I wasn't aware of its workings.
