Tandemloop Technologies Fullstack Developer interview questions

The interview process at Tandemloop Technologies involved an initial HR screening, followed by a technical interview that tested my full-stack development skills, problem-solving, and understanding of modern frameworks. The process was structured, professional, and allowed me to discuss my prior experience in detail. Overall, it took about two rounds to reach a final decision.

The interview process happened in multiple steps: First, they sent me a Google Form that had a few basic coding questions. I had to solve them and attach the solutions directly in the form. After that, there was a telephonic HR round where they asked about myself and some basic questions. It was mostly about my background and communication skills. Then, the technical interview was scheduled. I was given 3 coding questions to solve — I could use any editor and there was no strict time limit. I couldn't solve the 3rd question at first, but they said I could take my time and get back. This round went up to 2.5 hours, and eventually, I was able to solve all 3 questions. After clearing that, they scheduled another technical round but told me this time I had to code in Rust — a language I had never used before. They gave me 3 days to learn it, saying they wanted to check how fast I could adapt to a new technology. In that round, I got 2 questions — the first one was the same as before but had to be done in Rust, and the second was a pattern-based question that confused me a lot. They had removed some expected output values, and I was unsure if I was supposed to add something myself or not. It took me another 2.5 hours, and I still couldn't solve it completely. I told them I couldn't spend more time that day due to other commitments. They explained the solution and I told them the instructions could have been clearer. They also gave me a sheet covering all the topics expected in future rounds. I studied all the topics from that sheet, and in the next round, they asked me in-depth questions based on it — which I answered well. After that, they said the next round was scheduled. In the CEO round, they asked HR-type questions — about how I work, how the company works, my expectations, and theirs. They told me that the final HR round would be on Friday. But after that, I never heard back. No response to my follow-ups via call, message, or email. I even reached out to the CEO on LinkedIn — still no reply. Final Thoughts: Basically, they ghosted me after the final round. Stipend & Salary Talk: Stipend: ₹22K during 3-month probation After probation: ₹24K/month (PF deduction in this salary) I requested ₹24K in probation and ₹28K post-confirmation — they agreed. The job location was Bangalore, which was one of the key reasons I really wanted to work with them.
