I applied online. The process took 4 weeks. I interviewed at Exotel (New Delhi) in Oct 2018
Interview
There are total four rounds
1. Telephonic round: it mainly revolves around the work/project that you have done in the past and questions around that.
Once you clear this round, they will call you for an on-site round
Onsite round consisted of three rounds
2. Round 2: it mostly revolves around coding. They ask you to write code on the paper as well as laptop.
3. Round 3: Again a technical round, focusing more on infrastructure knowledge.
4. Round 4: combination of technical and behavioral questions.
Finally, if the above round goes well, there will be HR round.
