Interview
A few years ago I interviewed with Checkout.com at London. I was living abroad and I let them know my phone signal was very bad, but still, they decided to keep the technical interview on a phone call. During the call I mentioned several times I was struggling to hear and understand the questions, the recruiter ended the call and I wasn't moved to the next stage, they said I didn't have cloud experience, which wasn't true. Their recruitment team has contacted me several times over the last year asking me to do a first interview and, apparently, when they come to know about my first failure, they will never even arrange the first interview. They will say that I'm not fit for the role anymore, the role is closed, or any other excuses. Worth mentioning that I've never applied myself, I was always contacted on platforms like hired.com or cord.co. Their recruitment process is absolutely unrespectful and a waste of time and effort.

Question 1
No questions because they never schedule the interview. I don't remember the first interview questions as I could barely hear them, but there was something about messaging queue

Interview
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?

Interview
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.
