The Heights DNA (TL;DR)
Smart Supplement and 'Brain and Gut' product messaging require evidence of commercial judgment and evidence-based brand storytelling. Evaluators favor candidates who ground decisions in DTC retention metrics and clear unit economics rather than generic promotional tactics.
The Heights Interview Loop
Your onsite loop will typically consist of 4 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard problems, reasoning about defects, code clarity, edge cases.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Heights interview outcomes, avoid these common traps:
- Proposing a single massive database query to fetch all actionable subscriptions daily.
- Ignoring boundary edge cases where a plan change happens on the last day of a billing cycle.
- Failing to handle ties or scenarios where no single warehouse holds the full bundle.
- Neglecting memory overflow issues when storing intermediate matching states.
Test Yourself: Real Heights Questions
Three real prompts pulled from our database.

Frequently asked questions
How long does the Heights interview process take?
Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.
How should I prepare specifically for Heights?
Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.
Does this apply to engineering or design roles at Heights?
The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
