There were 2 interviews. The first interview was more about Java questions. There was also a software design question - ticketing platform. The second interview: I had to look at several examples of Java code and I had to answer what would the output be. The interviewers also asked questions about Spring Framework and Spring Boot.

it is a good process, and everything looks good, 3 round interview + hr round. then the whole process took around 1 month, with 2 weeks background check, finally I accept the offer.
