Dell Technologies Inside Sales Representative interview questions

I'd like to start by saying that the actual interview was a good learning experience, but the recruitment process before and after the interview was the most unprofessional experience. I got this interview after networking with sales reps and a talent acquisition advisor at a career fair. Great conversation overall, and they asked me to leave my resume and contact details. I then got contacted for an interview from some lady sitting in California. My interview wasn't confirmed till 30 minutes before my interview (which the sales reps told me was HR's fault). When I arrived for my interview, the HR person that I networked with saw me and obviously recognized me but chose to act like we had never met before. The interview was with 2 sales reps, and as mentioned above, that was a good experience. They were kind and open about the position. Post the interview, there were no updates, and my emails were ignored by that same HR person that I met and networked with at the fair. Really unprofessional and unwelcoming. I won't recommend Dell to any of my friends, specifically because of the lack of professionalism in HR. To other fresh grads, you deserve better than this.
