I've seen posts from about 15 or so people on my LinkedIn feed since August 5th announcing their undesired departure from Dell and all are seeking employment. The majority were in sales, but there were a few from engineering, sales, etc.
At the same time I've seen four announcements of people STARTING new positions at Dell. I can't tell if these are promotions or new hires, but the wording in the posts indicate they are new hires. Two appeared to be mid-level ISR management positions, one was a director level sales management position and the most recent one was an "SVP and GM Americas Medium Business."
I am only one data point and do not have a college business management degree, but it seems these four positions could have been filled by four of the 12,500 laid off or slated for layoff.
