Unpleasant experience.

All interview processing is informal, and the recruiter is not responding. I've received phone calls from their recruiters a couple of times. They walked me through compensation details and initiated a phone call with the hiring manager. Some very basic technical questions were asked, and they sent me a code assignment, which I completed. Then, once I had the on-site interview, the process looked good, except nobody came back with the result. After I reached out to the recruiter, he sent back an email stating they were very impressed by me but had lost headcount.

The second time was almost the same, except they asked me to do a code assignment and never came back again. Then, I did the same thing, asking again. After two weeks, they replied, stating although they were very impressed by my background, they wanted to move to other candidates.

I guess I should never try this company again, since they are so bad at recruitment. Also, I can see how messed up it can be if you go through interviews with this kind of company; it will waste too much time, not to mention you may spend a whole day on-site for nothing.
