DoorDash Software Development Engineer interview questions

Surprisingly challenging at times — I found the questions to be more complex than I was prepared for. The first round included a coding task to validate a shopping cart, which was tricky but doable. The next round involved a grid problem, where I had to find each cell's nearest source. What really helped me was the coding challenges I explored on prachub.com before the interview. Overall, I received an offer, but I ultimately decided to decline.
