I applied online. I interviewed at Trackier in Mar 2026
Interview
The interview process was smooth. HR clearly informed me about the rounds beforehand and scheduled them according to both my availability and the panel’s schedule.
There were two rounds:
Round 1: DSA + Node.js + backend theory. The interviewer asked me to open my LeetCode account and solve questions that I had not solved previously. I ended up solving one medium and one hard problem. After the DSA part, there were theory questions related to Node.js, proxy servers, and backend fundamentals. The round lasted around 40–60 minutes depending on the DSA time.
Round 2: System Design. I was first asked to explain one of my projects. The panel then picked different services and modules from the project and asked me to explain them in depth. The round was interesting but quite challenging.
For preparation, I would suggest focusing on understanding system design patterns well rather than only practicing common HLD examples like Uber or chat applications.

Interview
I made a mistake of not taking the above reviews seriously. I thought they are some salty interviewees who were uncapable to crack the interview. I was wrong. This whole interview process is a fluke. They clearly are not filling the role or they set me up for failure. I guess the HR has to justify her job which is why she sets up so many calls and follow ups. I had 2 Tech rounds which went amazingly well but they dropped me like a hot potato without even rejecting me standard rejection response. Instead, the mail goes something like "sorry we cannot proceed further". That's it. The interviewers do not turn on cameras. But you have to. Also, they will give you a useless LC problem for which the interviewer asked me to open my leetcode account and show that I haven't solved it before. Seriously? Is the interviewer thinking himself of Donald Knuth or something? Do not interview at any cost with this company. Or if you do, do not take it seriously because they will waste your time. Just use them for interview practice.

Question 1
Build a k-v data store. But bro didn't even tell me which features to implement. He just said everything right from basic operations to indices and practically everything. All in 40 minutes which is unrealistic. Oh, clean code btw, wait it has to work perfectly too. I was given so much to code in just 40 mins and I bet the interviewer felt smart after asking me to code all of that in such a short span.
