I interviewed for a TPM role at HubSpot a few months ago. Found almost nothing about what the TPM loop looks like there, so writing this up for the next person.
HubSpot's TPM function is a bit different from big-tech TPM roles. They're more cross-functional orchestrators than pure technical project drivers. You're expected to partner with engineering, product, and go-to-market, not just run sprints. Keep that in mind.
The process:
Recruiter screen was unremarkable. They asked about my background managing large cross-functional programs, stakeholder count, and scope of impact. Also: experience with HubSpot as a customer. If you've never used HubSpot, set up a free account and spend a few hours. The interviewers notice.
Technical screen (90 min, with an eng manager). They asked: Walk me through how you'd scope a technical project from discovery to delivery. I gave a structured answer: requirements gathering, technical scoping with eng, dependency mapping, risk register, milestone cadence. A hypothetical about a stalled migration project. "Two teams have conflicting priorities and the shared infrastructure migration is blocked. What do you do?" This was the real test. They wanted to see escalation judgment and stakeholder management, not just project management process. Some light technical questions: what's the difference between eventual consistency and strong consistency, when does it matter for a SaaS product. Not deep, but enough to check that you can talk to engineers.
Onsite (virtual, 4 rounds): Program design: design a cross-team program for launching a new platform capability. They gave me a vague scenario and expected me to ask clarifying questions, then structure a plan. This mirrored real work pretty closely. Behavioral: tons of cross-functional conflict questions. "Tell me about a time engineering and product were misaligned on scope and how you navigated it." STAR format, specific outcomes. Technical depth: more engineering judgment questions. Not code, but system design awareness (how would latency issues in this component affect the downstream product, etc.) Leadership/influence: HubSpot TPMs lead without authority. This round was almost entirely about influence, communication, and getting buy-in.
Timeline: 5 weeks total, 3 rounds of scheduling coordination (some friction there). Offer was around $185k base plus RSUs. Felt mid for the scope of the role, I negotiated up a bit.
Biggest tip: prepare a story where you unstuck a blocked cross-functional program. That comes up in every round.
