Senior Software Engineer Interview Experience - London, England
August 1, 2021
Negative ExperienceNo Offer
Process
- HR call
- Hiring Manager round (went very well)
- 4 hr coding challenge (did well)
- Code review from PHD Scientist (Went very well; he was impressed and had no comments on my code)
- Panel interview 1 & 2
- System design (Got positive acknowledgment for every system design decision/discussion I made; it went well)
- Panel interview 3
- Coding/Problem solving: Arrived at a solution with the best complexity, O(1). Even then, the reaction was not okay from the interviewer. Racist, as I'm from India.
- Panel interview 4
- Coding/Problem solving: Interviewer was totally impressed and happy.
At the end, I got an email on follow-up saying they could not proceed with my application, even though they received positive feedback. Basically, they want to play a racist game. Thanks, The Trade Desk, for wasting my time.
Guys, it's a time waste. Apply only if you know someone personally. They don't prefer real talent.

Best company ever, really excited to go to work every day!

March 19, 2015
Pros: Fun environment. It feels like a family. Technically challenging, fast growth. Working on a system that has to scale to above a million queries per second. Great snacks, awesome benefits: 401k matching, and medical is better than we had at Microsoft. Many offices and locations to choose from. Great opportunities as it is still growing fast.
Cons: Some locations are still very small, but the team is growing fast on all fronts.

Pros: Culture is really good. Everyone is nice and helpful. There's a high bar for engineers and lots of big, challenging tasks. Work-from-home policies are relaxed. The office is also great and has a good location. The kitchen is filled with snacks and drinks.
Cons: The engineering team is highly distributed around the world, and work activity really never stops. That can be good or bad, depending on your lifestyle.

Pros: Snacks, food, environment.
Work can be very interesting.
Cons: No CTO. Not an engineering powerhouse, though it does have talent that is underutilized.
Stock isn't very strong, with a high P/E.
