Microsoft Data Science interview questions

One of the worst experiences, highly unprofessional from Microsoft. Did not mention they are running a hiring drive, was made to wait for 4 hours literally and then evaluated for just a 10 min round with the most arrogant of the recruiters. All went absolutely well, and I was asked to wait for second round but then after 30 min of more wait, they came with the lamest of responses - "We will get back to you " . Clearly don't value the time of a professional, from where he is coming on a Sunday eve and in what circumstances. Clearly indicates how well you treat your prospective employees and how much concerned you are with their careers.
