Yahoo received my resume at my college's Career Fair. I received a phone interview opportunity two days later.

During the phone interview, the interviewer asked about Java fundamentals, database concepts, and SQL design questions.

I received an onsite opportunity one week later.

The onsite interview had four rounds:

• The first round covered CS fundamentals.
• The second round focused on Front End Programming.
• The third round involved reverse engineering and scripting.
• The final round was a discussion with the team manager.

How to get the depth of a tree.
