Totally unprofessional team, seems running college project.
My first round was with CTO of this company,It took around 1 hour.
As they don't have data engineering team, they scheduled my technical interview with some 3rd party.
That company took two rounds of technical rounds( I cleared both the rounds)
I received email for final discussion.
They have postponed the interview twice before 5 minutes of scheduled time.
Still I have sent an email , they revert with another time.
I joined that meeting but no one joined, after 15 min wait ,I dropped another email.
Still waiting for the response.
I have wasted around 5 hours of time in this process.
Instead of applying this company try to join some better company with professional team.
