A 14-Question Excel and SQL Online Assessment

The exam had 14 quiz questions total, with one big SQL question in the middle. The content was almost exactly like what people have shared here in past years — really grateful for those write-ups, they were super helpful for prep! Questions 1-7: you download a CSV file. The one I got was about an online ad platform — A/B testing, watch time, dates, that kind of thing. The HR email had actually me…

Four OA Problems Under a Tight Clock

The first problem was to figure out how many numbers in an array are a power of some number k. Basically you check whether repeatedly dividing by k eventually gets you to 1, but you have to watch out for the special case where k=1. The second problem was about a planet's lunar calendar: given the moon phase at the start of the year, compute the moon phase on a given date. The phases cycle every 8…

A TV-Show Cancellation Case, Then a Power Day Invite in 90 Minutes

Q1 - They asked the TV series case: assume you're the CEO of this company, and the company currently has a TV show called Analyst. When you're deciding whether to cancel this show, what factors do you need to consider? I answered from the revenue and cost angle. After I finished, the interviewer asked a follow-up, something like "do you think you need to consider the market situation?" I got what…

Three Case Rounds in One Power Day

This is my May interview experience. Since one of the cases hadn't been posted on the forum before, it took me a while to write this up. Round 1: Product case — this was similar to what's already on the forum. Round 2: They asked about the $300 over-limit transaction case, which has also shown up on the forum before. My attachment has it too. Round 3: This was a case I hadn't seen before, and I f…

A Recruiter Who Forgot They Recruited Me

In early July, a recruiter reached out to me proactively on LinkedIn, asking if I was interested, and said that if I was, they wanted to talk to me as soon as possible, as soon as possible, as soon as possible. I said sure, and figured the day after next would work. They vanished. Four or five days later, at 6pm, they called me directly out of nowhere (probably because my LinkedIn settings let re…

What are interview experiences?

An interview experience is a candidate's own account of a hiring loop — not a question bank entry. It tells you the shape of the process: how many rounds there were, what each round actually tested, how long the gaps between them ran, and what the recruiter said at the end. That context is the part a question list cannot give you.

How to read them

Weight recent write-ups more heavily — interview loops change, often within a year. Read several for the same company and role rather than one: a single account tells you what one interviewer asked, while five tell you what the bar is. Note the outcome badge too, since a rejection write-up usually explains the gap far more precisely than an offer one.
