Mixpanel·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026

PMM interview at Mixpanel with a scenario-based question about cross-team dynamics during a product launch. Short but not easy.

Your team is about to launch a new feature but morale is low and people aren't willing to collaborate. How do you handle it?

“I went straight to 'align everyone on the customer impact' which felt right but also kind of generic in hindsight.”

Mixpanel·Software Engineer·Technical Phone Screen

May 2026

Mixpanel software engineer interview with a pretty gnarly string arithmetic problem. No fluff, just one meaty coding question that took up the whole session.

Given two large decimal numbers as strings (no scientific notation, possible leading/trailing zeros), implement their exact sum as a string without using floating-point arithmetic or any big-number library. You need to handle alignment of fractional parts, carry propagation across the decimal point, and output normalization. Also discuss time/space complexity and cover edge cases like mismatched fractional lengths, integers mixed with decimals, all-zero inputs, and very large inputs.

“This one took me longer to get into than I expected.”

Mixpanel·Product Manager·Onsite - Product Sense / Strategy

Apr 2026

Mixpanel PM interview, one big strategy question about Google Pay monetization. Pretty open-ended and I wasn't totally sure what angle they wanted.

How would you grow Google Pay's revenue by 10X?

“I went straight to the payments infrastructure angle, merchant fees, B2B services, that kind of thing.”
