Box8 Interview Experience for Software Developer (On-Campus)

I am Final Year Mechanical Student from NIT. Recently BOX8 came to our campus for hiring Software Developers. Students of all branches were allowed to participate. Initially, we were supposed to fill a form that was a bit lengthy consisting of questions regarding Internships, projects, and basic HR questions. After this, the process consisted of 3 rounds.

Round 1(Coding Round): This round was conducted on HackerRank platform.

• We were given two coding questions which we were supposed to solve within 90 minutes.
• One question was of easy level on Array transformation and second one was of medium level testing knowledge of unordered maps.
• Questions were of 50 and 100 marks respectively. Plagiarism was strictly monitored as many students who successfully submitted both the codes were not selected for further rounds.
• I was able to code both the problems and was shortlisted for interviews. 30 students including me were selected.

Round 2(Technical Interview 1): Time duration was 45 mins. 2 interviewers were allocated for each candidate.

• They directly jumped to my projects and asked few questions about them.
• They asked me about my internship and dived deep into it.
• They also asked me some React questions as I mentioned React in my resume.
• Then they asked me to write some basic SQL queries testing COUNT, GROUP BY, and some other SQL commands.
• After this, they gave me a coding question: https://www.geeksforgeeks.org/print-all-pairs-with-given-sum/
• Starting from Brute Force to most optimized solution, I gave them 5 different approaches and they were satisfied by my solution.
• Second question was a String question: https://www.geeksforgeeks.org/reverse-words-in-a-given-string/
• I was able to answer this too.

VERDICT: 8 out of 30 students were selected including me.

Round 3(Technical Interview 2): Time duration mentioned was 45 mins but my interview extended to about 90 mins.

• The level of this interview was bit hard.
• Again, 2 interviewers were allocated for each candidate.
• They started asking me some questions related to backend like difference between local storage and session storage, the difference between cache and cookies, some questions about JWT and related topics.
• Then they asked some questions about Networking protocols, DNS Server, etc and I was able to answer most of them.Then they asked me to code for 2 questions.

Both were minor variations of below 2 questions.

2. https://www.geeksforgeeks.org/find-number-of-islands/

Interviewers were impressed by my approach to both questions. All the interviewers, including round 1 were very supportive and polite . Only 2 out of 8 students were selected for full-time opportunities.

RESULT: PLACED AT BOX8
