I applied through an employee referral. The process took 3 weeks. I interviewed at Kraken in Sept 2024
Interview
Below were the steps I went through for my interview process:
- Initial screening call
- General interview (asked about my experiences, how I work, projects I've worked on etc.)
- Architecture interview (given a scenario in advance of the interview and asked questions on how you'd improve performance)
Overall, I had a really good interview experience. Charlotte Brown, part of the Talent team, oversaw my application. She conducted my initial screening call, then managed the progression of my application up to the offer stage. She was a delight to work with, super friendly and professional, keeping me informed at every stage of the process, and answering any questions I had. I was given feedback in a timely manner, and they were very flexible with times for my interview process.
Each of my subsequent interviews were conducted by two engineers each (both times I had different interviewers). Everyone was super friendly, making it feel more like a conversation than a traditional interview. It gave me a good indication that the culture here is good, and definitely made me want to work here more so I was hoping I'd get an offer!
I applied online. I interviewed at Kraken (London, England) in Feb 2026

Application
I applied through Indeed. The process took 1 month. I interviewed at Kraken (UK) in Feb 2025
Interview
1st stage: Had a chat with a wonderful recruiter, set the stage for the whole interview process. Discussions about the company structure, team I would be working it, salary expectations and general question regarding motivation for joining the team.
2nd stage: Take home test. A django command line app for parsing file(s). Here, they evaluate you on taking on an ambiguous task and providing a scalable solution. Document your assumptions properly.
3rd stage: Further technical discussion about the task. Discussing approach, decisions taken and tradeoffs. How can the app be extended.
4th stage: The final stage. Focuses on your technical skills and the wider Python/Django ecosystem—discussions around ways of working.
After the last interview, the offer came within 30 minutes.
I really enjoyed working with my recruiter (Brad). He was super supportive.

I applied online. The process took 3 weeks. I interviewed at Kraken (Paris) in Nov 2025
Interview
Le processus d'embauche est très straightforward:
1. Un appel en visio RH
2. Un test technique à faire à la maison (3-4h) en Python, Django
3. Un appel en visio avec 2 ingénieurs pour discuter du test technique et des possibles améliorations
4. Un appel en visio avec 2 personnes de l'équipe (team fit)
Toutes les personnes que j'ai rencontrées lors de ces entretiens ont été très bienveillantes. Le processus est transparent et très rapide. J'ai eu des retours le lendemain de chaque entretien. Les retours peuvent prendre 1 semaine au maximum. J'ai aussi reçu un document qui expliquait tout ce processus, contrairement à d'autres entreprises où le processus peut être flou et long, donc c'était une agréable surprise. Franchement ce type de processus humain est très rafraîchissant, merci la team Talent Acquisition. De plus, la Talent Acquisition Specialist était au top, très à l'écoute et réactive.

Question 1
"Quand est-ce que c'est compliqué de faire un git revert?"
1. Screening call with recruiter to learn about the company, very chill
2. tech test
3. meeting with engineers who reviewed the test to discuss the solution and how you'd improve it
4. Culture fit and further technical discussion with head of engineering
Overall it's a *very* straight forward process with only a take-home test and 2 stages where you talk to people in the company. Compared to other companies that had 4+ stages not including the screening call it was very good to see someone still hiring sensibly. Offer came very quickly after the final call and I was delighted to accept. I was also treated very well by the recruitment team and it felt like the process was decisive and quick.
