Pros
Free food and snacks come to mind first, which says something about the rest. Flexible work timings are good to some extent. Analysts get to interact with clients from Day 1.
Cons
Its not enough to work 14 hours a day, you need to spend more time ''selling yourself'' otherwise there is no chance of promotion. All managers need to say a ''yes'' else no promotion, which is tough if you come in, do your work efficiently at your desk and have a life after work. Also there is wide variation in salary ranges - analysts doing the same work as their colleagues sometimes earn twice as much just because they are from a better college (and more often than not, the underpaid analyst is the better performer). Hiring processes are also unplanned - claims of taking in only 1% of workforce and going to good colleges only is all fine on paper, but when new projects come in, hiring from tier-3 and tier-4 colleges happens which leads to both differences in salaries as well as in abilities to do the job at hand. When I quit my job, the number of clients who reached out asking why I am leaving was three times the number of people in senior management at Fractal who asked me why I was leaving. Says volumes about getting (or not getting) appreciated at work.
