Pros
Free snacks (sometimes) available in the break room for when you were expected to work through lunch or stay late. You will appreciate previous employers (and future) much more after the experience. High turnover, so lots of new faces, and you likely will not be around long either after seeing how the place is run.
Cons
Inept, dishonest, and arrogant management. The "leadership" roles are filled with people who talk big, but cannot deliver. People are constantly hired or fired based on prospective deals that almost always fall through once the potential customer sees through the gimmick. If you end up coming here and are actually introduced to people, ask how long they have been employed. Also, try looking for their name plate of their desk to see if it matches - they have likely been shuffled around on "visitor" days in order to make the office seem full. Just search for the long list of previous BestIT employees on social media. Or instead of social media, just look at the "leadership" page of BestIT's website itself. Around ten of the twelve people listed are no longer with the company. There is a reason so many last for just a few months.
