There were 4 rounds in my interview. The first round was Resume shortlist, followed by one-on-one round. The third round was one-on-one, followed by final one-on-one round. No professionalism, got shortlisted for another profile in which I was interested into.

After clearing 3 rounds they said they have hired someone internally as preference is always given to internal employees first. Then they themselves forward my resume to another profile in which I was not having much experience. I got to know this in interview only as HR only told me that I am forwarding your resume to another team with same profile
