There are a lot of things, I will mention a few here.
1) Here is no work-life balance, Even for the name
2) Company can call any time, you should be available at any cost (This one is a major rule of the company), even I was getting a call 3 AM too(weekly thrice minimum)
3) No job security, How long you are working in the company doesn't matter You will be terminated over a single night without notice.
The company have a strong record of terminating employees,
1, 2, 3, 4 Year experienced people were terminated without notice over the night. every year average of 20-25 people will terminate.
For a Delivery manager, No one exceeds 2months ( for the last 3 years 15 delivery managers)
4) Politics playing a major role in this company,
5) Company side posted a positive review, don't believe those reviews.
6) Company has ready to give the salary what you asked because Company is playing with your desire and life too
