Pros
I guess it's obvious for people with low emotional quotient to blame the situation for their own downfall. Yes, these are the whiners you'd find on the Glassdoor posting reviews because they have enough idle time for whining instead of doing a little self-introspection and start finding a purpose in their lives.
C'mon, nobody can fire you if you are performing well because we all know that every company wants high-achievers to stay, no matter what. So no, I disagree with the people who are making statements that Jsimple is a hire-fire company; no, it's not.
Jsimple is not a charity, and obviously, if somebody can't pull his/her own weight, then he/she will merely bring the other high-achievers down and Jsimple can't afford to lose its star performers because of the whiners. Yes, at times, companies have to let these poor performers go because if we're riding a bus and your destination doesn't match with where our bus is going, you'd better get off sooner than later. We respect your time and expect the same in return.
We love crazy, curious, and hard-working professionals and know how to keep them on board.
Cons
It's not for the people who are looking for a Govt. job of 9-5 (especially if you're going to work with the development team and clients overseas). It's a fun environment only for the people who love what they do and aren't working just for the money.
