Hotstar Interview experience
Location: Remote, India
Position: Backend Engineer
Years of Exp: 2.1 years
Resume shortlisting
First step was resume shortlisting. I applied for the role directly on Hotstar Career's portal and after 1 months I was contacted directly by the hiring manager who was hiring for one of their teams.
1. HR call
Got phone call from HR, where I discussed my experience and how I am suitable for the role. He asked soem generic behavioral questions regarding leadership and my motivation to join Hotstar. He told me everything about the process, expectations, etc. He told me about the interview process.
2. DSA Screening (1 hour)
After basic introduction from both the sides, interview started with DSA based question which I had to code on any IDE. Question he shared on zoom chat. Medium leetcode level question, one medium matrix question. (longest consecutive one's in a matrix (can be horizontal, vertical, diagonally, antiDiagonal)).
3. DSA-2 (1 hour)
After basic introduction from both the sides, interview started with DSA based question which I had to code on any IDE. Question he shared on zoom chat. One easy level (valid parentheses), 2. Given a xml file, extract some fields, convert it to hashmap, then perform some string operations. (can use google for this). Didn't like the boring question, it doesn't look like an DSA round to me.
4. LLD (1 hour)
After basic introduction from both the sides, interview started with designing Stock exchange platform to match buyer seller, and store the order in a table. Wrote java code, all the entity, their functions. Ended with us discussing why i think Priority queue will use be better for performing order match, and other time complexity space complexity questions. How HashMap can be used to store the entries for future reference. etc. This round was more like a good interesting DSA round for me.
After i cleared all the rounds I got a call for 2 more rounds (HM round and Bar raiser round).
5. HM round (1 hour)
After basic introduction from both the sides, interview started with behavioural questions, challenges i faced, best project i worked on, my learnings. etc. Didn't go well, as they asked me how you mesaured your feature. what was performance matrix. (never heard of these terms before). Remaining half questions were on Machine learning. Like which data set i used for a particular project. explain that project. how you decided model, which accuracy i used etc.
6. Bar raiser round (1 hour)
After basic introduction from both the sides, interview started with a HLD question. In which they asked me to design swiggy. explained every part. Ended with me asking some questions from the interviewer.
I was 50-50 sure after my HM round. Completed all the interviews in 3 days and got rejection mail on the next working day.
Because of this interview I got motivation to study LLD and HLD so thanks to Hotstar.
I hope this will assist anyone preparing for a Hotstar interview.
