The Unobravo DNA (TL;DR)

Matching patients with specialized therapists like a Psicoterapeuta Relazionale requires rigor around clinical triage metrics. Interviewers test your ability to balance clinical matching efficacy against user retention metrics, evaluating patient-psychologist matching trade-offs.

The Unobravo Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard problems, reasoning about defects, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Unobravo interview outcomes, avoid these common traps:

Insufficient data encryption (at rest and in transit).
Using a simple list and performing linear scans for all operations.
Not implementing monitoring and alerting for potential issues.
Not considering potential performance implications of complex filtering logic.

Test Yourself: Real Unobravo Questions

Three real prompts pulled from our database.

Type · Data Structures

Unobravo stores therapist availability slots. Implement a data structure that allows efficiently adding new availability slots, removing existing ones, and finding the next available slot for a client within a given time range.

Type · API Design

Design a simple API endpoint for Unobravo's client-therapist matching system. It should accept client preferences (e.g., issues, language, availability) and return a list of suitable therapists. Consider the request and response formats.

Type · Algorithmic

Given a list of user sessions on Unobravo, where each session has a start time and end time, write a function to find the maximum number of concurrent sessions at any given point in time. Assume sessions are represented as tuples (start_time, end_time).

9 of 12 questions shown

Recruiter Screen

1
Type · Motivation
What interests you about Unobravo's mission to make mental health accessible, and how do you see your software engineering skills contributing to that goal?

Coding Screen

2
Type · Algorithmic
Given a list of user sessions on Unobravo, where each session has a start time and end time, write a function to find the maximum number of concurrent sessions at any given point in time. Assume sessions are represented as tuples (start_time, end_time).
3
Type · Data Structures
Unobravo stores therapist availability slots. Implement a data structure that allows efficiently adding new availability slots, removing existing ones, and finding the next available slot for a client within a given time range.

System Design

4
Type · Scalability
Unobravo's user base is growing rapidly. How would you design the backend system to handle a 10x increase in concurrent users, particularly focusing on the real-time communication features (e.g., chat between client and therapist)?
5
Type · Reliability
Imagine the therapist scheduling system experiences intermittent failures, leading to double bookings or missed appointments. How would you design this system to be highly reliable and fault-tolerant?

Onsite Coding

6
Type · Debugging
A client reports that sometimes their messages to the therapist are delayed or lost. You have access to server logs and the message queue. Walk me through how you would debug and resolve this issue.
7
Type · Algorithmic
Unobravo wants to implement a feature to suggest related articles or resources to users based on their therapy topics. Given a list of user topics (strings) and a knowledge base of articles (each with a list of associated topics), design an algorithm to find the top K most relevant articles for a given user. Define 'relevance'.

Behavioral / Leadership

8
Type · Conflict Resolution
When balancing the need for rapid feature deployment on the Unobravo platform with the rigorous security requirements for sensitive patient data, describe a moment where your proposed technical implementation faced pushback from a team member. How did you reconcile the technical trade-offs while keeping the patient experience at the center?
9
Type · Ownership
We often see patterns in our logs where therapist-client matching latency spikes during peak evening hours. Tell me about a time you noticed a performance bottleneck or a recurring user friction point in a production system that wasn't currently on the team's sprint backlog. How did you validate the issue and drive the fix from discovery to deployment?

Frequently asked questions

How long does the Unobravo 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 Unobravo?

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 Unobravo?

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.
