DoorDash Interview Questions
DoorDash records 301 questions and splits almost evenly between engineering and data. Software Engineer accounts for 146 of them and Data Scientist for 118, with small counts for machine learning, analytics, and product roles. Analytics & Experimentation is the biggest category at 74, ahead of Coding & Algorithms at 65, System Design at 40, Behavioral & Leadership at 37, and SQL and Python work at 28. Onsites hold 141 questions and technical screens 131, with only 5 from online assessments. Ratings run 181 medium, 76 hard, and 20 easy. The engineering prompts are service-shaped rather than puzzle-shaped. Candidates report building a three-service refund workflow over HTTP, making a courier pay workflow resilient to downstream failures, and filtering open restaurants through existing domain APIs, plus design rounds on an alert notification service and a refund workflow modelled as a directed acyclic graph. Debugging appears directly, in one case round-robin against consistent-hash routing. Behavioral questions carry real weight, covering a project you recovered after it went off track, making every team member's voice heard, and an ownership project with measurable impact. 35 questions were added in the last 90 days, 1 round is tagged AI-assisted, and 41 first-hand interview experiences are on the site.
Practice with Claude Code or Codex
Your agent opens a real question, interviews you, and grades you against the model answer.
"I got asked a hardcore MCM DP question and I saw it on PracHub as well. Solved that question in 5 minutes. Without PracHub I doubt I could solve it in 5 hours. Though somehow didn't get hired, perhaps I guess I solved it too fast? /s"
"Believe me i'm a student here jn US. Recently interviewed for MSFT. They asked me exact question from PracHub. I saw it the night before and ignored it cause why waste time on random sites. I legit wanna go back and redo this whole thing if I had chance. Not saying will work for everyone but there is certainly some merit to that website. And i'm gonna use it in future prep from now on like lc tagged"
"10 years of experience but never worked at a top company. PracHub's senior-level questions helped me break into FAANG at 35. Age is just a number."
"I was skeptical about the 'real questions' claim, so I put it to the test. I searched for the exact question I got grilled on at my last Meta onsite... and it was right there. Word for word."
"Got a Google recruiter call on Monday, interview on Friday. Crammed PracHub for 4 days. Passed every round. This platform is a miracle worker."
"I've used LC, Glassdoor, and random Discords. Nothing comes close to the accuracy here. The questions are actually current — that's what got me. Felt like I had a cheat sheet during the interview."
"The solution quality is insane. It covers approach, edge cases, time complexity, follow-ups. Nothing else comes close."
"Legit the only resource you need. TC went from 180k -> 350k. Just memorize the top 50 for your target company and you're golden."
"PracHub Premium for one month cost me the price of two coffees a week. It landed me a $280K+ starting offer."
"Literally just signed a $600k offer. I only had 2 weeks to prep, so I focused entirely on the company-tagged lists here. If you're targeting L5+, don't overthink it."
"Coaches and bootcamp prep courses cost around $200-300 but PracHub Premium is actually less than a Netflix subscription. And it landed me a $178K offer."
"I honestly don't know how you guys gather so many real interview questions. It's almost scary. I walked into my Amazon loop and recognized 3 out of 4 problems from your database."
"Discovered PracHub 10 days before my interview. By day 5, I stopped being nervous. By interview day, I was actually excited to show what I knew."
"I recently cleared Uber interviews (strong hire in the design round) and all the questions were present in prachub."
"The search is what sold me. I typed in a really niche DP problem I got asked last year and it actually came up, full breakdown and everything. These guys are clearly updating it constantly."
