I applied through an employee referral. The process took 3 weeks. I interviewed at Observe.AI (Bengaluru) in Jun 2020
Interview
There were several rounds.
1. Discussion with the Hiring Manager
2. Technical Round (Basics)
3. Technical Round (Projects and experience)
4. Technical Round (Hands-on Round)
5. Another discussion with the hiring manager.
6. Discussion with HR.
All the interviews were done through video calls.
The whole process took around 3 weeks.
Talent acquisition team was very prompt with replies for all my queries.
I was sent a detail about what the next discussion will be focusing on beforehand. This helped in my preparation.
I personally enjoyed the Hands-on round. The interviewer helped me understand the problem and guided me to arrive at a solution through the discussion. The questions were unique and intuitive.
Over all it was a positive experience. All the interviewers were more focusing on Knowledge that we posses and the depth of it.
