Google·Product Manager·Onsite - Product Sense / Strategy

May 2026
Got a product design question at Google and it was pretty much just the one: design a smart fridge. Felt like a lot of ground to cover in a single question.
  • How would you design a smart fridge?

“I went straight to features and the interviewer kind of just waited.”

Google·Software Engineer·Onsite - Coding / Algorithms

May 2026
Google SWE coding round with a board game simulation problem. Pretty straightforward premise but the details matter more than they look.
  • Given a string representing a board where 'T' is a token, 'C' is a coin, and '.' is empty, calculate how many coins can be collected if tokens can move across the board (each coin collected only once).

“My first read was 'oh this is just count the C characters' and I nearly said that out loud.”

Google·Machine Learning Engineer·Technical Phone Screen

May 2026
Interviewed for an ML engineer role at Google and got hit with one of those conceptual explainability questions early on. Not a bad experience, just a bit disorienting when you're mentally prepped for math.
  • How would you explain computer vision to your grandmother?

“I fumbled this a bit because I went too technical at first, started talking about pixel arrays and then caught myself.”

Google·Product Manager·Onsite - Product Sense / Strategy

May 2026
Google Pay PM interview with a single case question about responding to a hypothetical second demonetization of the Rs. 100 note. Pretty intense scenario that forces you to think across immediate ops, product changes, and long-term strategy all at once.
  • You're the key decision maker at Google Pay India. The government has just announced demonetization of the Rs. 100 note. Walk through your immediate, short-term, and long-term response.

“This one is sneaky because it sounds like a crisis management question but it's really a product strategy question dressed up in policy clothing.”

Google·Software Engineer·Technical Phone Screen

May 2026
Interviewed for a business analyst role at Google and got hit with a visualization question about churn that seemed straightforward but made me realize I hadn't thought deeply enough about the analytical side of the role.
  • What types of visualizations would you use to identify patterns in customer churn?

“I went with the obvious stuff first, survival curves and cohort retention heatmaps, which felt solid, but then I kind of rambled into scatter plots without really tying them back to churn specifically.”

Google·Software Engineer·Onsite - Behavioral / Leadership

May 2026
Behavioral round at Google for a software engineering role. Just one question but it took up the whole conversation, lots of follow-ups digging into the specifics of what I actually did versus what the team did.
  • Tell me about a time you advocated for someone else during a team situation, such as a junior colleague or a stakeholder whose perspective wasn't getting enough attention. What did you do and what came of it?

“I had a decent story ready but I kept second-guessing whether my example was senior enough.”

Google·Product Manager·Onsite - Product Sense / Strategy

May 2026
Google PM interview, single question, product design format. Pretty open-ended and I wasn't sure how deep to go on the technical side versus the user side.
  • Design a lawn mower.

“My first instinct was to jump straight into features, which was probably the wrong move.”

Google·Product Manager·Onsite - Product Sense / Strategy

May 2026
Google PM interview, one big open-ended product design question covering basically everything: user scenarios, MVP scoping, architecture, and scale. Felt more like a mini system design session than a typical product sense round, which threw me off a bit.
  • Design a photo-sharing app where users can upload, view, share, and download photos across multiple devices. Walk through user scenarios, the MVP feature set, the system architecture (clients, backend, storage, sync), and how you'd think about scaling it.

“I started with user scenarios which felt right, but I spent way too long on the fluffy persona stuff and barely had time for the architecture piece, which is clearly where they wanted to go.”

Google·Product Manager·Onsite - Product Sense / Strategy

May 2026
Google PM interview, one question about diagnosing latency issues. Not much else to report, pretty short session.
  • How would you approach diagnosing and resolving a latency problem in a product?

Google·Technical Program Manager·Hiring Manager Screen

May 2026
Interviewed at Google for a TPM role, got asked what makes someone effective in the position. Pretty short on details but it's a question worth thinking through carefully.
  • What qualities make an effective Technical Program Manager?

“I talked about cross-functional coordination, technical credibility, and knowing when to push vs.”
