I applied in-person. The process took 1 week. I interviewed at Letstrack (New Delhi) in Feb 2020
Interview
The whole process was easy as they wanted to understand your intend to join the firm post which they ask you to do a task. Basically a test regarding a superficial campaign.
Interview questions [1]
Question 1
Why would you want to join our firm and would be comfortable with a contract facility if there would be of any kind ?
