Interview
I had my interview process with concrete4change around Sept-Oct 2024. I got an initial call with the CEO Sid first as an informal meet-up, which was a very nice interaction and introduction to the company.
I was given a case study to submit in 1 week. It was a research based exercise, which in retrospect, is very important to gauge the way you think and what kind of topics you will be exposed to at the company.
Shortly after submitting my response, I was invited to the company for a formal interview (they offer to cover all expenses). I was able to spend the day shadowing an employee to get exposed to the type of work and environment.
Within 2 weeks, I received my offer, and shortly after, a video call with the CEO and CTO (Sid and Michael) to discuss my offer and plan.
While it was a tough interview process, it was fair and very interactive, and having been at C4C for almost 4 months now, I see that this process is crucial to keep a high level of performance within the company and an exemplary attitude.

Interview
Michael promises great conditions but asks you to complete an "assignment". In it you have to produce a full-sized report on extremely technical problem, which is obviously something they have issues with. The report must be exhaustive and he REFUSES to compensate it in ANY form. Effectively the company uses a predatory practice using applicants to solve their tasks as free labour.
You can tell that initial offer is too good (90k) because even director there gets 70k approx.
Additionally, interview is for a leadership position and there was no board except him. For a small company I would expect CFO, CEO or a tech expert.
