I thought it was a positive experience overall, although I feel they were only looking for people with sales experience so they were always doubting my motivation for the position. I prepared A LOT (read all glassdoor reviews, multiple calls with the internal referral, read through all webpages/case studies, and all materials they sent me) so I didn't think the process was that difficult in terms of company knowledge. I guess my weak point was in expressing my passion for sales.
