Please suggest some good companies

My friend is from tier 1 college 2023 batch, currently working in Microsoft as a Software Quality Engineer with 15 LPA, good benefits but bad work life balance. He is thinking about switching to a new company with some benefits on priority. He is good in problem solving and a knight on leet code.

What's your opinion on the details below?

1. Role: SDE
2. Minimum CTC : 15 (Base) LPA
3. Work life: Flexible Hours, No strict deadlines, No overtime.
4. Employees Count: 500+
5. Tech Stack: Any Top Backend framework.
