Several things I need to bring up here about my experience....
1) Problem solutions to secure the interview can be found in Hackerrank, since they use this to filter out candidates.
2) If you get through the hacker rank questions, you will then do a pair programming exercise.
3) If you do well on that....
In my experience, after the pair programming exercise, I didn't hear back from them. I tried calling the recruiting director several times and she did not return any of my calls. Is this a professional company or a big fat joke? It is usually considered polite to tell someone whether or not they are getting a offer, much less getting trained, since that's what they CLAIM they do. I find their lack of professionalism disturbing.
