Tl;Dr- They took 1 technical MCQ test, 1 Psychometric test, 3 technical discussions. The results of all these were postive. They scheduled one techno-managerial round but cancelled the round once I joined on time, citing that the manager got held up in a meeting and would reschedule. That reschedule never happened. Total waste of time. I would avoid even thinking about this company.

The recruiting HR reached out through LinkedIn DM.

First round was an MCQ test, to be completed in 15 minutes or so. Difficulty Level - Hard

Next round was a 60 minutes bug fixing and code refactoring round. The interviewer shared a link to some online coding platform where I had to fix some bugs and later needed to make the code more pythonic. This was of easy difficulty. The interviewer was super friendly and cooperative. Got the positive feedback about this round the same day within 1 hour.

The next round was a system design and coding round interview. Had to code a flask framework code to develop url shortening service. I found the difficulty to be moderate and interviewer to be communicative and friendly.

The next round was another python technical round with a senior technical interviewer. Questions were pretty theoretical and the interviewer showcased okay behaviour and seemed disinterested too. Duration- 1 hour. Got a positive feedback for this round though.


Next a techno-managerial round was scheduled. It was termed as stakeholder evaluation. I joined on the scheduled time and then got to know that the interviewer was busy and the call would be rescheduled. The call was never rescheduled and after 1-2 weeks, upon following up with the HR, it was told that the position has been filled internally. Seriously ?😬 Then why bother with so many rounds.

I had moved on to different interviews. After 2-3 months, Lab49 HR comes back and informs that the interview would resume again.

The HR wanted to have a fresh discussion and booked a time slot for the next day. The HR again doesn't join.

After a few days comes back again apologising and citing their busy schedule. Finally after asking a lot of repetitive questions, like the details about the work experience etc, asks to take up a psychometric kind of test. They inform that in early September(which was after 10-15 days) they are going to complete the remaining round of the interview process.

After psychometric test, the feedback is okay but the next round never happened.


This is one of the worst interview experiences I ever had. They kept on dragging the process and killed my 4-5 hours unnecessarily. Thankfully, I had continued with other companies and had got offer there too. I would strongly advise the company to be clear about their hiring plans before scheduling any interview.
