The myTomorrows DNA (TL;DR)
Connecting physicians with pre-approval medicine via Expanded Access Programs requires candidates to balance regulatory compliance with patient urgency. Evaluation centers on how effectively you navigate clinical trial data and articulate risk-benefit trade-offs to pharma partners.
The myTomorrows Interview Loop
Your onsite loop will typically consist of 5 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. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of myTomorrows interview outcomes, avoid these common traps:
- Using inefficient full-graph traversals for every patient match query without caching node reachability
- Treating hierarchical disease taxonomies as flat strings, failing to recognize parent-child medical code relationships
- Failing to account for missing or unrecorded patient profile attributes during condition evaluation
- Executing heavy sub-queries for optional criteria before verifying simple mandatory criteria
Test Yourself: Real myTomorrows Questions
Three real prompts pulled from our database.

Frequently asked questions
How long does the myTomorrows 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 myTomorrows?
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 myTomorrows?
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.
