Haven't seen such an unprofessional company. They call you for interview on a specific time and then make you wait for as long as 2 hours for a hardly 5 minutes f2f round.
After that they asked you to leave and according to them there HR will contact you for result and that's the most hilarious part because you never get that. Even if you mail them to ask they don't even reply on that.
There developer has a specific set of questions which are not updated too and if you fail in answering even one, so sorry you are not upto there requirement.
Grow up guys respect others and there time.
