Once you have applied for a position, these are the steps involved in hiring process.
1. Talent Acquisition Partner will reach out to you and will explain the company details, job description and expected budget for the position plus benefits. If you are fine with the role and salary range, he will setup first technical interview.
2. Hiring manager will conduct this interview and will ask some technical, design and architectural questions. If this goes fine then there will be detailed technical interview.
3. This will be in-depth technical interview with Team Lead and Senior developer.
4. Third and las interview will be a formal HR interview to understand and evaluate your behavioral and interpersonal skills.
5. Once HR interview is cleared, you will receive formal offer letter/contract and onboarding will start.
Questions d'entretien [1]
Question 1
They ask you whether you are comfortable with the role and open to work in new tools and technologies.
I experienced the interview process as very disrespectful. Only during the feedback conversation after my rejection did I learn that the position had effectively shifted toward a mid‑level role, something that had not been communicated to me beforehand. I was told that this feedback that I am, somehow, actually a mid level developer (despite covering the job of a senior) was told to me “for the sake of my future.” In my view, questioning a candidate’s seniority, especially when they have already held comparable roles for years, is inappropriate. I ultimately accepted a senior position elsewhere with higher compensation and full remote, without mandatory “pillar days” of attendance or whatever you called it. For me personally, remaining unemployed would have been preferable to working here.

Question 1
Mostly technical coding questions that in my opinion really relied on mnemonic knowledge and became obsolete after LLMs

The process started with an initial screening round, followed by a technical interview with system design and then a round with deeper technical discussion with code review. The team was professional and direct throughout the process. Communication from HR was clear and timely.
The interviews were heavily focused on core Python fundamentals, concurrency concepts, messaging systems (queues, Kafka/RabbitMQ), transactions, and system design. The technical depth expected was quite high, especially around language-level concepts such as context managers, decorators, and concurrency primitives.
In the later round, the discussion became very detailed around Python internals and low-level constructs. When I wasn’t able to confidently explain a specific core concept (context managers), the interview was concluded early with the feedback that for a Senior role, strong fluency in core Python fundamentals is expected.
What I liked:
Interviewers were technically strong and clearly knowledgeable.
Questions were practical and relevant to backend engineering.
Clear feedback was given directly.
What could be improved:
The process felt somewhat unforgiving; the interview was ended early based on one foundational gap rather than evaluating overall system design and backend experience.
A slightly more holistic evaluation of seniority (architecture, real-world impact, problem-solving) alongside language fundamentals would make the process more balanced.

The interview process consisted of a recruiter prescreening call, followed by an interview with the engineering manager, and finally an in-depth technical interview focused on problem solving, system design, and practical engineering skills.
