Pros
Work life balance is exceptionally great. Salary is very good compared to the work load. Perks are too good: food, transport, medical insurance. Most of the work is maintenance with relatively no work responsibility. No need to develop new skills. Fixed mindset of most colleagues facilitates no stress. Most employees are relaxed and chilled, facilitates happy life. Management has no vision and it is very easy to convince them that you are working.
Cons
No growth mindset. Colleagues are mediocre software engineers. One cannot grow in career. Little to no software development opportunity. Appraisal system is not transparent. Need to do politics to get good ratings. To get any work done you need to have personal connections. Otherwise people will keep saying they are busy!
