I applied online. The process took 3 months. I interviewed at Intercom (Dublin, Dublin) in Feb 2018
Interview
I applied through LinkedIn for the first time but wasn't shortlisted. I applied through StackOverflow the second time almost a year later and got a callback.
- The interview process was long and thorough, with a strong focus on writing code, culture contribution and product thinking
- The first step is a take-home assignment that tests your programming skills and how comfortable you are in writing code
- It is followed by a telephonic round, that tests your problem solving with a programming language of your choice, and culture contribution
- I had another full round of culture contribution since there wasn't enough time in the first phone call.
- If all goes well, you are called on-site - which packs a full day of interviews, from programming problems, problem-solving, product design and culture contribution.
- I did not actually get an offer after the on-site since one of my rounds went totally sideways, which was a little disappointing since all my other rounds went pretty well
Fast forward 4 months ---->
- I got a call back asking if I am still interested in the role (which I was)
- They gave me a chance to give it another shot at the round that did not go well the first time, I was able to clear the second time
I applied through a recruiter. I interviewed at Intercom (Berlin) in May 2026
Interview
I was contacted by a recruiter on LinkedIn and agreed to take part in the interview process. Received an email days later about the full interview process. If you are attentive here, you'd see the question for the problem solving interview. Unfortunately for me I wasn't able to finish it under 50 mins as I had to process my thoughts and explain them as I code. I thought I did enough to at least get to the next round but apparently I didn't.
I applied through a recruiter. The process took 4 weeks. I interviewed at Intercom (Dublin, Dublin) in Sep 2025
Interview
One Leetcode style question, hiring manager chat, small edit on an existing project and a data modelling round. No system design interview for any level. Mostly worried only about data modelling for some weird reason.
Interview questions [1]
Question 1
Priority Queue based leetcode, college level chat system like project to make edits, another RDBMS related stuff, then a weird hiring manager chat.
Recruiter screen, then role-specific task (coding or written). Next comes a technical/values interview, followed by a multi-round onsite: pair programming, system design, product chat, and cultural fit. Process is structured and thorough; candidates highlight strong organisation but note occasional tooling issues and slow feedback.
Interview questions [1]
Question 1
Tell me about a time you improved something without being asked, why did you do it, what was the outcome, and how did others respond?
