      Difficult interview

      I interviewed at Power Factors

      Interview

      At least 3 interviews were conducted and it was harder ones and eventually stretched to the CEO interviews. I thought the recurring process was way longer than I expected and I felt this keeps going on forever.

      I interviewed at Power Factors

      Interview

      I went through several rounds of interviews with the company. I had technical interviews with the team. The atmosphere was friendly and conversational, and the team made me feel comfortable throughout the process. The technical questions were mostly straightforward coding problems that tested basic problem-solving and programming skills, nothing too tricky or unexpected. I had another interview with the recruiting manager.Everyone I spoke to was respectful, professional, and genuinely interested in understanding my fit for the role. Finally, I had a short follow-up meeting with HR.

      Easy interview

      Application

      I interviewed at Power Factors (Stockholm, Stockholm)

      Interview

      The interview process consisted of three key steps: Call with HR – The initial step was a conversation with the HR representative, where they provided an overview of the company, its culture, and the role. They also asked questions about my background, experience, and career goals to ensure alignment with the position. Coding Challenge – After passing the HR screening, I was given a coding challenge to assess my problem-solving skills, algorithmic thinking, and proficiency in the required programming languages. The challenge was well-structured and tested both efficiency and code quality. Technical Interview – The final stage involved a technical interview with engineers from the team. This session included discussions about my coding challenge solution, system design concepts, and real-world problem-solving scenarios. It also covered my past projects, technical expertise, and approach to collaboration within a development team. Throughout the process, everyone I interacted with was polite, professional, and friendly, making the experience smooth and enjoyable.

      Average interview

      Application

      I applied through a recruiter. I interviewed at Power Factors (Athens, Athens, Attica) in Jan 2024

      Interview

      The interview process is straightforward yet demanding. It begins with an HR screening, followed by a practical coding challenge to build a smart, functional UI using a tricky API. If you pass, you move to a technical interview with the hiring manager and a senior developer. This stage feels comfortable and collaborative, focusing on day-to-day pull requests rather than trick questions. Finally, you visit the office to meet the team in person.
