Entrevista
There were 4 parts:
- one initial phone call with internal recruiter
- home technical test
- first face to face interview with 2 senior developers and the development manager
- second face to face interview with a technical lead and the director of engineering
In the initial phone call we discussed about the company and myself in general terms.
The home technical test had clear requirements - development of API for shopping list management and integration with Checkout Core API Client.
The test was preliminary for the face to face interviews.
The first face to face interview was with HR manager, 2 senior developers and the development manager.
Technical questions were asked, my profile was discussed in more details.
Financial aspects were also discussed in the first face to face interview.
Also I got the chance to ask questions and I'm satisfied with the answers provided.
The second face to face interview was with a technical lead and the director of engineering.
I was asked questions for every line in my CV and requested to provide clear details of my experience, working challenges..
Also behavioural questions were asked (like "What does upset you most about people?")

Entrevista
The best interview process that I had so far . Starts with a survey after the recruiter screening which is very detailed for the candidates to align with the company culture, with a clear feedback on the end. The challenge at home with a task that makes sense for the domain of the company was the next one, followed by a live explanation of the project I liked much more than the traditional pair programming rounds, as it removes a bit the pressure of live coding which eventually brings problems totally disconnected of the position that we are applying and gives you the time to discuss your solution with the interviewers afterwards. The final stages, system design and values interview in person are much more enjoyable and feels more like a workday at the office with a colleagues than live interviewers made on-line.
Up until the system design it was really friendly. Then it became the most embarrassing interview I’ve ever had.
The guy visually facepalmed and laughed if I said something he didn’t like. Asking a lot of trick questions and said hashing the API Key when storing in the database doesn’t make any sense. 😆

Why would you hash an API key when storing in the DB?

I had a first-round interview with talent acquisition, followed by a take-home test, and finally an in-person interview focused on system design.
During all three steps, I received positive feedback. However, after a call from the HR team informing me that I had successfully passed all the steps, they suddenly told me I was not successful due to some gaps in system design and the coding challenge from the second-round interview. This felt quite strange; it seemed like they didn't know what they were doing.
It is possible to successfully pass all interview stages and still not progress with your application, which I find unprofessional.
