In the interview, a coding test and survey questions were given. The recruiter sent me an e-mail with a link to the hacker rank. There was a time limit of 48 hours for the link to expire. As a result, I must take the test within the next 48 hours. I took some time to study before the interview, and then I sat down. There were a total of five questions in the coding portion of the test. A maximum of two hours twenty minutes is allowed. In addition, a few 20-minute survey questions were also asked.
Difficult interview
Application
I applied online. I interviewed at Next Solution Lab in Mar 2022
Interview
After applying for this post it took 1 month for them to reach out to me. The interview process is divided into two phases both phases were online
1. Coding Exam
2. Interview (Technical Interview + HR Interview)
Coding Exam: In the coding exam they gave 5 problems and 19 survey questions
You will get 2 hours 40 mins to solve and answer the survey questions
The survey question was about myself like can you work at the office if remote is not possible? something like that
and the problems were based on Data-structure and Algorithms.
after the coding exam, they called me at night saying tomorrow will be an interview.
Interview process: The whole interview process took 1 hour 30 mins to complete this section is divided into 2 parts
1. Technical interview
2. HR interview
Technical Interview: 5 people took my technical interview and first they asked me basic python questions then they went deep into machine learning
HR interview: HR asked me about the survey questions and the reasons behind my answers
