Overall, it was a pleasant process. I had one phone screen and was brought onsite next week. The onsite interview consisted of six parts:

• Past project deep dive
• Two front-end questions
• One data structure question
• Two cultural interviews

What really got me was the data structure part. I probably spent too much time on it, so I couldn't finish it in time. After being rejected, I found the question is actually one of the top 10 popular questions on LeetCode and is categorized as hard. I think if you are not a LeetCoder, solving it in time does have difficulty.

I was not comfortable after knowing that the question is from LeetCode, but I think that's what everybody is doing right now: pick a question from LeetCode and hire an engineer who is good at LeetCode.
