Demandbase Customer Support Engineer interview questions

During my phone screen, my interviewer was asking me questions that made it obvious he was worried I would not stay long at the position. I thought I answered them well, and he said he would send me an assignment to do since he wanted to move me to the next round. Yet as he was telling me that I had made it to the second round, he sounded incredibly detached and as if he were just going thru the motions. I suspected he was going to flake on me. I was right. He never bothered sending over the assignment I was supposed to do. Lying to a candidate about moving them to a next round is incredibly disrespectful and unprofessional. I’d rather he just said they would consider me for the next round rather than lie that I had made it. Apply elsewhere.
