I applied online. The process took 2 days. I interviewed at Calypso Technology (Mumbai) in Jan 2017
Interview
There were 3 rounds of interview:
1. Telephonic Interview. It was detailed covering all important topics of core Java like OOP concepts, Multithreading, Collections, Exception Handling and Java architecture related questions such as JVM, JRE, JDK, 32 bit and 64 bit Java.
2. F2F interview. Puzzles were asked.
3. Interview with Manager. Explanation about the role and job details. Some questions about yourself.
Then I was told that I will get a call from HR. But I didn't get the call. Maybe because my salary expectation was high.
