I was emailed that the phone interview is going to be behavioral, however once I answer the call I was told that it is going to be a technical coding challenge. I solved the questions in 30 mins, however the interviewer was not satisfied with the result by mentioning they are not effective solution.

I applied for an opening in August through an employee referral. They contacted me for an interview in November and made an offer in late December. HR was completely unwilling to negotiate on anything but I accepted anyway with a start date the second week of January. On my way home from my last day with my previous employer HR contacted me to let me know that due to logistical issues my start date was being pushed back an additional week. Not cool. Icing on the cake is that they also stiffed the guy that referred me on the referral bonus claiming that they don't offer one even though management had been touting the bonus even after I started.
