Servient Software Developer interview questions

The first time Servient called me , I was surprised as they don't have any HR dept. in Houston I believe so their VP called me for interview. They called me on a working day (Thursday) Afternoon. The Interview was easy, one in person coding exercise , then another developer asked Algorithm question , then after that they organized a small meet and greet with CEO . Everything went well , the next day the VP told me they are going to forward me the offer on phone and mailed me also the same. I was excited to work for them , since it was the Friday , that guy told me that they are going to forward me the offer on Monday , I waited on Monday and I asked them when I am expecting the offer , no reply to my calls and mail. I again tried calling them on Wednesday. No reply this time too. By this time I was sure there is no offer coming so I asked if they can please tell me if I am getting the offer or not and I'll understand even if there is no offer. No reply. I am glad I didn't join the company. Such unprofessionalism shows loose morale and work ethics in company. Later people told me they don't give salary on time. I'm glad I didn't get the offer. Dodged the bullet.
