Entrevista
I was contacted by recruiter and they have acheduled for a initial round via google hangout. There was no clear information on interview format. I was not aware that there would be coding interview. Since I was attending via mobile there was a hiccup to do coding round.
Feedback was given after 2 weeks and 4 email followups. Standard reply saying that they want pursue with other candidates. Not going to give interview in future as I am not happy with interview process overall.

During the interview process, everyone I took interview was super polite. But on the hand hr was only replying ones in a week(Friday) and if we need to speak it had to be arranged for next week. At the end, when I couldn't pass the onsite they didn't say anything until I ask. (for 10 days)
