Hey guys,
Couple of my friends have co-founded InterviewBit ( https://www.interviewbit.com ) which helps with preparation of coding interviews. They also help with referrals to great tech companies. They have already placed more than 200 people in companies like Zenefits, Uber, Facebook, Google, Microsoft and Amazon.
All of this is done for free.
You can reach out to Anshuman ( One of the co-founders ) at Anshuman@interviewbit.com if you have any feedback.
