I applied via LinkedIn and was interviewed in Jan 2024. There were 2 interview rounds.

Round 1 - MCQ round on your technology 

(1 Question)

  • Q1. MCQ on nodejs and javascript
Round 2 - Assignment 

Second round was node js assignment, I completed these two rounds and after two weeks they are responding that I am rejected , they wasted my efforts which I did in completing assignment and trust me I did my assignment very well, there was no chance that anyone can reject that.
They are just wasting your time, please don't invest too much in them.
