Next, you'll have a one-hour coding interview focusing on CS fundamentals. Expect textbook algorithms and data structures. They will focus on how you organize your code, test, and debug, along with how you think and your communication skills.
Finally, there's a virtual on-site interview. This consists of four rounds, totaling 4-5 hours. You can complete this all in one day or split it up.

- 5.0Fast Growth, Great BenefitsSoftware Engineer • Current EmployeeSan Francisco, California, United StatesNovember 27, 2017Pros: DoorDash is growing fast, either in company size or in its business. Things are moving fast too. The company and teammates encourage a culture of giving feedback on everything and on product ownership. Working hours are flexible. You decide what to do and when to do it, as long as teammates are positive on these contributions. You will want to run fast because everyone around you is fast. The internal infrastructure toolchains are pretty good too. With them, you can have development environments within 1-2 days. You will contribute right after joining the company without suffering from configuration delays. Benefits are very good too. * Buffet lunches are provided every day. * Reimbursements for parking and transportation are provided. * Sequoia Swift Benefit is used to provide dental, vision, and medical benefits. You can set them up on your own.Cons: Too many things to do, and almost everything needs negotiation. Sometimes there are many context switches in one day. It's not really a con but evidence the company is growing and needing more workforce. It just requires more effort from you to prioritize things.
