Google·Machine Learning Engineer·Onsite - System Design / Architecture

Apr 2026
Got a system design question for an ML engineer role at Google. Pretty open-ended, which I wasn't fully prepared for.
  • Design a system that removes noise from audio signals.

“I started with a pretty basic spectral subtraction approach and the interviewer just kind of waited, so I figured they wanted more.”

Google·Software Engineer·Onsite - Multi Round

Apr 2026
Did the full Google loop for a software engineer role in Europe, made it through the behavioral screen, phone screen, and first onsite fine, then completely choked on what turned out to be the easiest problem of the whole process. 12-month cooldown. Painful.
  • Given a stream of chat messages as strings, identify the most talkative participant in a group conversation.
  • Two strings that are initially identical but too large to fit in memory have each been modified by a series of edits. Determine whether the two strings are still equal after those edits.
  • Given a graph, solve a traversal problem involving connected components using Disjoint Sets (Union-Find).
  • Given two arrays, determine which elements to remove from the second array so that its first k unique elements do not overlap with the first k elements of the first array.
  • Describe a past project where you faced significant challenges. Walk through what went wrong and how you handled it.

“Felt pretty good about this one.”

Google·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Google product interview, one question about how YouTube's recommendation system works under the hood. Pretty open-ended and I wasn't totally sure how deep to go on the technical side versus the product side.
  • How do you think YouTube's video recommendation feature works?

“I started with user signals (watch time, clicks, skips) and tried to connect them to the ranking logic.”

Google·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Google PM interview with a single open-ended product design question about air travelers. Not a lot of context to go on, but it's the kind of prompt that can spiral fast if you don't anchor it early.
  • Design a product for air travelers.

“Super broad, which is either a gift or a trap depending on how structured your thinking is.”

Google·Software Engineer·Onsite - Behavioral / Leadership

Apr 2026
Behavioral screen for a Software Engineer role at Google, just the one question about weaknesses. Pretty standard but I fumbled it more than I expected.
  • What is your biggest weakness? Give a concrete example, describe how you became aware of it, and explain what steps you have taken to address it.

“I had a generic answer prepared and it showed.”

Google·Product Manager·Onsite - Behavioral / Leadership

Apr 2026
Google PM interview, behavioral round. Just the one question but it hit harder than I expected.
  • Describe a situation where you had to bring two teams that were in disagreement to a common resolution.

“I had a story ready but halfway through I realized I was spending too much time on the context and not enough on what I actually did.”

Google·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Google PM interview with a single product design question around memorializing pets. Pretty emotionally loaded prompt for a product sense round, which I wasn't expecting.
  • Design a product to help people memorialize pets that have passed away.

“I went full feature-mode for the first two minutes and the interviewer just kind of waited.”

Google·Technical Program Manager·Onsite - Product Sense / Strategy

Apr 2026
TPM interview at Google with a pretty meaty compliance and strategy question. Just the one question from what I can tell, but it had a lot of layers to it.
  • How would you design and roll out a GDPR compliance program across Google's services?

“This one is bigger than it looks.”

Google·Software Engineer·Onsite - Multi Round

Apr 2026
Went through a multi-round Google SWE interview and now stuck in the waiting game. Coding rounds had follow-ups I didn't fully finish, but both interviewers said the incomplete ones were bonus questions, which is either reassuring or just what they say to everyone. The Googleyness and Leadership round felt genuinely good, ran almost an hour and turned into more of a conversation.
  • Solve a coding problem and then work through follow-up variations on it.
  • Follow-up coding question where the interviewer had a specific solution in mind.
  • Behavioral and culture-fit interview covering how you work, what motivates you, and why this company.

“Got the main problem and first follow-up done fine.”

Google·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Interviewed for a PM role at Google, got a data-focused question that felt more analytical than I expected for a product round.
  • How would you check for bias in your data?

“I fumbled the opening a bit.”
