The hiring process is very bad. Initially said there will be 3 rounds. 2 technical and 1hr. I have cleared both the technical rounds. Then recruiter called and asked for HR round. Then after 2-3 days they decided to have one more technical round. If you want to reject someone please don't let them clear 1st 2nd round only. Wasting someone's time is very bad. 1st round - core Java, java 8, Spring boot, microservices questions, java programs using stream. 2nd round - similarly on java, java 8, Spring, project related questions 3rd round- how you will build insta, location app, WhatsApp, and there architecture

-If you want really want to switch then dont give an interview. -After clearing both the technical, Management will create the problem. They are not scheduling further rounds and show you a wrong hope about next rounds. -Final Comments:- If you want to give mock interview then definitely try.
