Perguntas de entrevista de vagas de Program Manager da empresa CDW

I had a really terrible experience interviewing at CDW. They were quick to contact me. Had me do 4 interviews within 4 week. Never disclosed the salary range !! And then the manager calls me on the spot to do a 2nd interview without pre scheduling it ahead of time. Which was inconsiderate. He also told me CDW , hasn't done layoffs in a long time and 3 months later they layoff 600+ people. Additionally, I had to put together a sales presentation for the interview. For a product I didn't know anything about. Ultimately, I was not selected. Altho the manager told me about the start date timeline and added me on LinkedIn. I immediately removed him after the recruiter emailed me to tell me they didn't hire me. Don't waste my time !!! Also, call the candidates who jumped through hoops for you , to tell them over the phone. Very unprofessional.
