I was invited for a L1 interview by a recruiter named Benjamin. After setting up the interview I tried contacting the recruiter several times for my queries regarding the interview process cleared. He never cared to respond back. And today morning 2 minutes before the scheduled interview time, tada! the interviewer pings me in Linkedin not to join as the interviewer has an emergency. I mean where is the courtesy? Where is the official email? And he just vanished into thin air. No responses further. Everyone's time is precious. This has been the worst experience for me so far! No professionalism and not even basic communication skills nor manners. Such a pathetic people management wing Altimetrik has. Beware of this recruiter reaching out to you!
