1. Hackerrank: 120 minutes (1 Leetcode medium, one easy).

2. Phone Interview with Lead: Discussion about Java and topics from my resume.

3. Skype Interview with Chief Software Engineer and directors (2 rounds).

The Chief Software Engineer was one of the most uncivil people I have ever encountered. He didn't know how to dry run code; I had to tell him where the recursion ends and how it ends.

Interview (His video was turned off):

Me: Hi .

Him: Okay, so you know my name. Let's start. What is DAG? (I told him what DAG is). Okay, you'll remove a node from a BST. I wrote 80% of the code. He stopped me in the middle and said, "You leave it, just insert the node for me."

I asked if there was something wrong with the removal code. He got offended and said, "Do you really think this will work?"

I explained my thinking and did a dry run of the code, which he was not able to understand. He interrupted a lot and then said, "Yes, this will work."

Then he said, "We just have 10 minutes. Solve a SQL question for me." I wrote the query. He said, "That's not how we write it. HR will get back to you. Bye."

If you have such a high ego, please don't take interviews.

1. DAG traversal.

2. Remove a node from BST.
