I am an experienced Software Engineer with 4 years of experience.
I was sent an OA from Amazon but I could not take it. HR was kind enough to schedule a telephone interview instead.
This was my first interview in over 4 years. The interviewer asked me to go over my resume and after which he asked me a very simple question on Binary trees. I could have easily solved it, but somehow I blanked out and I could not think well. I missed out on a lot of edge cases. But, after coming up with the algorithm with the interviewer's help I coded it up in less than 10 minutes and got the code pretty much correct. The very next day, I received a rejection email. I cant believe I messed it up so bad.

I have now started solving LeetCode again. I wont give up until I get a job offer, hopefully from Amazon!
