Process
The questions weren't hard in particular. For the first half hour, I feel like my interviewer was just working on his own work and not really paying attention. He started to interact more when I got a little stuck, but I was just talking to myself for a good half of the interview.
Questions
Given a matrix and top-left/bottom-right coordinates, calculate the submatrix sum.
This can be achieved in two ways:
- In linear time, with preprocessing.

Good Perks, Toxic Culture
Software Engineer • Current Employee
June 11, 2021
Pros: - Food
- Insurance
- Facilities
- Marketing
Cons: CTO changes every 2 years, and policies/ideas can be bi-polar if you look in the long run.
Senior management does not represent the middle-lower food chain to the CEO well. The upper food chain is in its own world, and no one cares to ask about front-line workers.
Senior tech leads have pre-conceived notions about the tech stack. Cost/effort estimates are overlooked.
The tech stack has massive issues, always in fire-fighting mode. There is no design/tech lead per se, only a namesake. More tactical efforts than strategic are made to get to another day, week, month, and then you get a bonus, rinse and repeat.
Literally face a tribunal when issues happen.
Forget about work-life balance, including on weekends.
Heavily under-resourced across teams.
They pay you above the market rate but make you work at least 2X.
No learning opportunity.
Too much politics.
