Rivian Software Engineer interview with panel interviews and a project presentation
I went through a fairly organized, conversation-heavy process. It started with an HR call, followed by a longer meeting with the hiring manager. After that, I had panel-style interviews with several interviewers from different teams. Each round included time for questions and follow-ups. The format combined behavioral and technical fit without feeling like a trick. In one of the later sessions, I…

Rivian Software Engineer interview with robotics debugging
The process felt fairly straightforward from the beginning. The interviewers were friendly, and we spent a lot of time discussing my actual projects and what I worked on day to day. Early on, I realized the role had been described in a way that blended into a systems engineering focus in the autonomy space, and the questions matched that impression. One round focused on systems thinking and how I…

Ro.Co Senior Applied AI Engineer Interview Experience — One-Hour Take-home on Aptora, Rejected the Next Day
Ro.co: there are basically no interview reports for this company on the forum, so I'm sharing a data point. It's based in NYC, a telehealth startup that's been around for several years, and its main competitor is Hims & Hers. I interviewed for a Senior Applied AI Engineer position. My background is traditional SWE, and I applied blindly online. I talked to the recruiter and the HM separately firs…

Robert Half Financial Analyst interview: reading red flags in spending data
The recruiter-to-interview path was straightforward, and I got the impression they were moving quickly because they had several hiring needs. For the technical part, I received a spending spreadsheet for an account and had to identify patterns that might be red flags. The follow-up went past basic background questions. We covered my work history, salary expectations, and the software I had used.…

Robert Slack Software Engineer interview experience
A few business days after applying, I received an interview invitation and began with a HireVue-style recording. It was highly automated: I read behavioral prompts and had a small window to record each answer on camera. I could redo answers a couple of times, but there was no interaction or sense of whether my answers landed. Near the end, the same session included coding. I could not ask clarify…

Robinhood Data Scientist Interview Experience — Sample-Size Math in the Experimentation Round
I've been getting rejected a lot in interviews lately. Today I got another rejection — they said my performance in the experimentation round wasn't good. I felt like I did really well in that round; I covered all the concepts I'd prepared ahead of time. I honestly don't see what was bad about it. For the experimentation round, they asked about the benefits of launching fractional shares and how t…

Robinhood Frontend Engineer Interview Experience — Three Onsite Rounds, Strong Self-Reviews, Still No Match
Three onsite rounds: Coding — Weekly Calendar Write a 7-day weekly calendar live, with columns as time (1-hour intervals) and rows as days. Clicking a cell pops up a dialog to create an event name. They give you a mockup. I wrote two pieces of state — a 2D grid and an events list — and did a transformation to derive the grid from the events. I felt like I wrote it so-so. The interviewer told me d…

Robinhood Senior Software Engineer Interview Experience — Passed the Tech Rounds, Failed the EM Round, Redid Team Match
I interviewed for Senior Software Engineer on the Competitor Insights team. I passed the technical rounds, but failed the EM round because I lacked frontend experience. The recruiter agreed to let me redo team match, so I talked to the Experimentation team as well. Round 1: Hiring Manager We covered the usual collaboration and communication questions, and I was also asked a lot of questions about…

Robinhood Software Engineer Interview Experience — Fractional-Share Inventory
The author describes a first-round Robinhood coding interview about handling customer trades when an exchange accepts only whole shares. The exercise tracked fractional inventory by symbol, covered purchases and sales, and included orders expressed either in shares or in money. Exchange transactions had to leave each inventory balance nonnegative and below one share after an order. The supplied f…

Robinhood Software Engineer Interview Experience — Load Factor, Reachability, and Explaining the Approach
The coding question was the classic load factor problem and was essentially the standard version. At the beginning, I asked whether I could assume that every node was reachable. The interviewer said yes, so I implemented the solution under that assumption. When I finished, it passed three of the four tests. I then started adding an explicit reachability check. My main advice from this interview i…

Robinhood Software Engineer Interview Experience — Referral Graphs and a Job Scheduler
The applicant reports completing Robinhood’s three-hour onsite across three separate days. A referral-count coding problem went smoothly, but the project discussion was harder: the applicant struggled to explain the system’s complexity and scalability after the interviewer exhausted questions about business logic. The report advises preparing useful starting points for a deeper technical conversa…

Robinhood Software Engineer Interview Experience — System Design Round Ended Early, Rejected in 9 Minutes
A bit of background: I graduated in 2021 and did four years of C++ SDK dev, mixed in with about two years of building a Python test framework. My company started requiring three days a week back onsite, and the commute was wearing me out, so I started looking for something closer to home. Robinhood's infra work wasn't really a match for my background, but they gave me an interview anyway, and in…

Robinhood Software Engineer Interview Experience — The Referral Chain Leaderboard Problem
Robinhood's referral program is pretty well known. The task is to build a dashboard to track the state of the referral program, specifically to understand how people refer others through a referral chain. Assume a person refers everyone below them in the chain. For example, A refers B, C, and D in a referral chain A -> B -> C -> D. Build a leaderboard showing the top 3 users with the most referre…

Robinhood Software Engineer Interview Experience — Two Months of Team-Match Limbo, Then a 'Role Moved to Toronto' Excuse
This has been an extremely long timeline, and even now I still don't know whether they want to reject me but can't bring themselves to say it, or whether they're just pretending it's still a team match. If any of you are at Robinhood, please help me figure this out. Thanks! Feb 11 — talked with the recruiter. Feb 19 — first technical round, they said I passed. Then another prep call with the recr…

Roblox Data Scientist Interview Experience — A Brutal OA With Robot-Building and Factory Games
First-time poster here. After I got the OA, I asked the career center for an extension but didn't get one, so I ended up squeezing it into one evening of Thanksgiving break, a week before finals deadlines. After I finished I felt like my English was terrible and my IQ had dropped :((( It seriously wrecked my mood for the rest of finals prep. 25 minutes building a robot car. There were two rounds…

Roblox Data Scientist Interview Experience — An Onsite Derailed by a Disrespectful PM
Roblox is a really hot pre-IPO unicorn, and lately they're hiring a lot, so a lot of candidates are interviewing there. I get it, a lot of people want in, but I have to complain a bit — the experience was, if anything, worse than others I've seen on this board. After the IPO the stock will probably pop, but long-term it's genuinely hard to say. Phone screen 1: HM The hiring manager was pretty nic…

Roblox Data Scientist Interview Experience — Nailed the Case Study, Still Rejected After Round One
(QS 50-100 school, physics PhD, desperately job hunting.) First round, technical interview, 60 minutes. The interviewer asked about my resume for 5 to 10 minutes first (my own work also has some connection to DS). Then two simple pandas data-processing questions using a bit of basic statistical test knowledge. I didn't need to run test cases, I just had to make the interviewer understand my code.…

Roblox Intern Data Scientist Interview Experience — Gamified Assessment and a Meta-Style Product Sense Case, No Offer
This application season I applied for Roblox's PhD DS Summer Intern position.

Roblox Senior Data Scientist Interview Experience — Python, SQL, and Rejection at the Hiring Manager Round
I applied online among lots of other applications, and HR reached out afterward. The overall process was HR screen → technical → HM. I failed at the HM round and didn't make it to the onsite. The HR phone screen was fairly standard, mainly asking: Self-introduction. Why are you leaving? Why Roblox? What are you looking for in your next role? The technical interview lasted an hour and mainly cover…
