They are not serious about hiring and interview process. They didn't give a proper feedback. I have to ping them multiple times to schedule an interview. Hackerank online test was not good, editor was buggy, I spend lot of time to understand the behavior. It gives error at false line.

Short interview with the team leader, he introduced the product and role and asked about relevant experience. Following this interview you get programming assignment to complete at home. The assignment was interesting, but you should provide more test data, since a big enough data set requires lots of testing. Didn't pass the assignment, next step is VP RND interview
