Applied from naukari. Got a call immediately to appear for a coding challange on hackerrank. After the coding challange, the interview process started. It was a telephonic interview. TBH, it was the WORST interview experience I ever had. The interviewer was rude, having one dimensional thought process, eager to make assumption and conclusions and mostly by the book. He does not let me complete my answers and tried to conclude on half way. Does not let you explain yourself and put his words in your mouth. The questions were easy, one puzzle based on pNc which I didn't answered correctly. If you are appearing for a java/spring dev 1. Prepare OOPS concept. 2. Basics of spring 3. Some 10th standard mathematics. Though I suggest to look for better place to as I can sense the working environment will be a lot terrible if you have these kind of interviewers working along with you in team. Best of luck!
