First-hand accounts from people who interviewed at Toast Inc.
Software Engineer
My interview experience at Toast was a bit unusual compared to big tech companies. It felt like they have this strict binary yes/no checklist, and you're supposed to say exactly what's on it, instead of really showing your problem-solving, leadership, or architecture skills. For instance, they don't really care about the logic behind your code, just that it runs. And for system design, they're not looking for the best solution, but a specific SQL query. While this might work for them, this kind of interview style relies more on luck than actual skill. On the plus side, the recruiter was really upfront with feedback.
- Can you introduce yourself?
Software Engineer - Android
Booking interviews was super easy with a link they sent, letting me pick a time that worked. The technical partner I spoke with was really clear and gave me all the info I needed, and it was a nice chat. Then, I had a technical interview with a senior Android engineer where we did some coding and talked about different things. Sadly, they told me the role was already filled even though my technical interview went well. I'm hoping for another chance with them.
- Discuss your experience with Jetpack Compose.
- What are your strategies for Android Testing?
- Explain Clean Architecture in the context of Android.
Software Engineer
The interview experience was really smooth and the recruitment team was super responsive and nice to talk to. It started with a quick screening call, then a technical interview where I had to solve a LeetCode-style problem. The final stage had two technical interviews and two behavioral interviews with the Engineering Manager and Project Manager. It was mostly good, though the second technical interview in the final round was a bit tough because I had some trouble understanding the interviewer's English, and we spent a good chunk of time discussing a minor detail in my code, which wasn't the most productive use of time. But otherwise, it was a positive and respectful process, and I'm glad I got to go through it.
- For the first technical round, the question was: Given an array representing stock prices on each day, find the best time to buy and sell to maximize profit.
