How long does the Aircall 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 Aircall?

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 Aircall?

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.

The Danger Zone: Top Reasons Candidates Fail

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

Not clearly articulating the 'why' behind the vision or strategy.
Blaming the other person entirely without acknowledging their perspective.
Focusing only on the outcome without detailing the influence process.
Using a simplistic relevance score that doesn't capture nuances.

Test Yourself: Real Aircall Questions

Three real prompts pulled from our database.

Type · Influence

Describe a situation where you had to influence a cross-functional team (e.g., Product, Engineering, Sales) to adopt a technical solution or approach they were initially resistant to. How did you gain their buy-in?

Type · API Design

Design a simple API endpoint for Aircall that allows a user to retrieve their recent call history. Specify the HTTP method, URL, request parameters (if any), and the structure of the JSON response.

Type · Real-time Features

How would you implement a real-time presence indicator for Aircall users (showing who is online, on a call, or away)? Consider the technologies and architecture needed.

Recruiter Screen

1
Type · Motivation
Why are you interested in Aircall specifically, and what aspects of our mission or product resonate with your career goals as a software engineer?

Coding Screen

2
Type · Data Structures
Given a list of user call logs (each with a user ID, start time, and end time), write a function to find the user who had the longest total call duration within a given day. Assume call logs can overlap.
3
Type · String Manipulation
Aircall's platform handles international numbers. Write a function to validate if a given phone number string is in a plausible E.164 format (e.g., +12125551212). Consider country codes, area codes, and length variations.

Onsite Coding

6
Type · Debugging
Users are reporting intermittent issues where call recordings are sometimes corrupted or missing. Describe your process for debugging this issue, from initial report to identifying the root cause.
7
Type · Algorithm - Hard
Aircall wants to implement a feature to suggest relevant contacts to users based on their call history and frequency. Design an algorithm to recommend the top N most relevant contacts for a given user, considering factors like call frequency, recency, and duration.
