Moody's interview questions

In all interview was easy, interviewer was frank and even appreciated me few times for my academic record. I believed that my interview was good and I had chances of landing the job. But, 4 weeks have passed with no response from the HR even after mailing them few times. It is bad to keep the candidate in dark for so long. At least inform them if they did not clear the process. No professionalism at all.

There were 4 sessions total each with 2 managers taking turns asking questions. We got about 20 minute breaks in between sessions. There were 2 white board sessions, 1 math/data science related and 1 behavioral/goals.
