Had an in person interview and then I was told I would be called back with the response. 2 weeks after, I have received a call late evening from a recruiter extending an offer. The next morning I was asked to interview with someone else as a formality and then a week later I was told that I didn’t get the job. Poor internal communication. That was very unprofessional.

Simple and easy, standard interviewing process with no difficulty. Just prepare and practice basic interview questions that you expect, and you shall be fine. That is all you need to do.
