I applied through a recruiter. I interviewed at DoorDash in Sep 2023
Interview
I was approached by a recruiter and then there was technical screen. My interviewer was okay, English was not their first language. I came up with an algorithm that passed all the test cases. Few days later I got a reject with 0 feedback and explanation. Considering I solved a Leetcode hard problem I am extremely upset that I was rejected. I would have been okay if there was any feedback. However they have a company policy against it, ROFL what?

Question 1
Given a binary tree, find the maximum path sum from any two "alive nodes" within the tree. We can assume a node is an alive node if and only if it is a leaf node, indicated by an asterisk below. Example 1 5 / \ 2 0 / / \ *25 *14 *15 Expected answer: 47 = 25 + 2 + 5 + 15 Example 2 5 / \ 2 0 / \ / \ *100 *50 *4 *15 Expected answer: 152 = 100 + 2 + 50 ***/
coding online assesment virtual onsite. interviewers were professional and helpful. asked to deep dive on project. recruiter was responsive and could align with offer deadlines. was helpful with negotiations. coding problems were average difficulty.
Walking into the coding interview, I was taken aback when they asked about finding the K nearest restaurants based on coordinates. Just days before, I had stumbled on a mock on prachub.com that mirrored this question almost exactly. The interview felt straightforward, but I struggled with some behavioral questions. Overall, the experience was underwhelming; I expected more technical depth. After several rounds, they decided to go in another direction, which was disappointing given my prep efforts.

Given a list of restaurants with their coordinates and a user's location, find the K nearest restaurants
it was very easy, they ask basic programming questions, can be solved with minimal prep, however they ask a lot about why u want to work here, be prepared to talk for a long time
