I was called by the HR after I was referred by a friend working in the company. After a brief discussion, my resume was shortlisted. I was then called for a F2F interview. I first had a technical round. Following that, I had a discussion with the manager. The HR had later contacted me via phone and gave the offer via email

You will get a call once your profile is shortlisted followed by 3 rounds. if all goes well within 15 days you will get offer letter Interview process is smooth and clear
