Hey guys,
Couple of my friends has co-founded InterviewBit ( https://www.interviewbit.com) which helps with preparation of the coding interviews. They also help with referrals for Android developer positions to great tech companies in India, Europe and US. They have already placed more than 200 people in companies like Zenefits, Uber, Facebook, Google, Booking, GrabTaxi, etc.
All of this is done for free!
You can reach out to Anshuman ( One of the co-founders) at [address removed] if you have any feedback.
