The interview was of duration 1 hour.

• Please be prepared with a dot to dot explanation of your Resume as I was grilled on that for more than 20 minutes on a 1 hour interview.
• The interviewers wanted to know in depth that why I want to leave my current job.
• They asked below questions:
  1. Post order traversal of Binary tree without recursion
  2. Detailed difference between Spring and Spring boot
  3. Dependency injection in detail
  4. Most challenging task in my last 2 years of job.

I was able to answer all the questions but I could not code the 1st problem even though I explained my approach correctly. I was very nervous because I had high hopes so I messed up.
Hoping my experience helps.
