Pros
Easy to change domain /technologies within company. Good for freshers ASE who start career from here. Maximum things depends here on projects/managers and good things number is less.
Cons
No hike for 2-3 years for experienced lateral employees who changed company and joined them. Variable pay is a dream come true! If you ask hike reply is "you can change job and get hike". Max 40k-50k per annum though actual variable would be around 1.3L- 1.8L for mid level employees 5-8yrs experience. Each time supervisor will compare with other seniors who would be having 9-10yrs of experience. Maximum of the projects have no work/time limit 11hrs a day is something very normal for months. Senior members/managers continuing in same company for decades and clarifies you have to maintain good relationships if you want to survive in respective IG's and high level of politics to maintain their position/value.
