Wayground Interview Questions
& Process

It's common nowadays to ask for a detailed assignment even when the candidate's profile and experience don't match the job. Quizizz did this, and I spent a lot of time and effort on a very thorough assignment. I saw a similar review on Glassdoor where they asked candidates (in Canada) for a similar assignment but didn't intend to hire. If they aren't looking to hire senior candidates, why waste everyone's time?

So the interview process at Quizizz for Senior Software Engineer was pretty intense, with 5 rounds total. It kicked off with a phone screen call. Then, there was a technical screen where they checked my DSA skills (medium level) and also some low-level design stuff, using a vending machine example. The onsite part was tough too, but organized. First onsite was more DSA, they gave me a rainwater trapping problem but with a twist to handle leaks. Second onsite was all about high-level design, asking me to design parts of Twitter and how recommendations work. Third onsite was focused on low-level design, like building a movie ticket booking system. The interviewers were professional and clear about what they wanted. Quizizz also covered travel and hotel for the onsite part, which was nice. It was a challenging process but gave a good overview of what the job needs.

The interview process at Quizizz was pretty unique. It kicked off with a deep dive phone call with the TA team. They explained the company's business, the roles, and how the process would work, and also got to know my background and goals. The whole thing had three parts: an initial call, three rounds all in one day at their office (super convenient!), and then an assignment presentation you could do remotely or in person. Round 1 (remote) focused on past projects, prioritization, and data, lasting about an hour. They gave feedback the same day and highlighted areas to work on. I got to pick my date for the office rounds. Round 2 (office) was about business understanding and identifying opportunities. Round 3 (office) covered UX, GTM strategy, and MVP. Round 4 (office) mixed behavioral, product sense, and cultural fit questions. They really take care of you there – snacks and a free meal during breaks, plus goodies afterward. Debrief was the next day, followed by a call for the final round with an assignment. I had total flexibility on when to submit it. They even set up a call with a senior PM to help with any questions, and the TA person gave some good advice on tackling it. Round 5 (office) was the assignment presentation. The assignment wasn't about their product but a well-known global one, and you didn't need to submit it beforehand. It really tested all PM skills: problem discovery, creativity, feasibility, trade-offs, wireframing, planning, and measurement. I found out the outcome the same day and got an offer discussion soon after. The entire process, from the first TA call to the offer, wrapped up in under a month. I appreciated their focus on transparency, quick communication, and flexibility.

It was like any other product based company's interview. We had 3 technical rounds and then a Higher Managerial round. The first round was a machine coding round on BarRaisers, where I had to build a frontend app in 1.45 hrs using any tech I liked. The last 15 mins were for questions about my code and general web dev stuff. The second round focused purely on javascript for an hour, with deep dives into concepts like closures and hoisting. The third round was an architectural one, which was the hardest for me, covering CSS, JS, Networking, HTML, Security Protocols, Testing, scaling, and more. The fourth round was more of a discussion about my personality and my interest in the company.
