I applied online. The process took 1 day. I interviewed at Coding Ninjas (New Delhi) in May 2020
Interview
You have to complete any particular course with a score of 90% or above to get shortlisted for the position. After that, you have one online test based upon the course. That's it.
Mid level question were asked about dsa and some HR type questions although it get well from my end but I got selected for teaching assistant role. It's a good opportunity for students.
The interview was online and they asked about concepts of data structures in C++. Then they asked some HR questions to check communication skills and to see if the candidate is fit for the role
Online test was conducted online on their platform of coding ninjas it was easy i already applied for dsa course. So just got to take the test and nothing else.
