  • Q1. Kubernetes, Kafka and Golang discussion
Round 3 - One-on-one 

(1 Question)

  • Q1. High level Design round

Interview Preparation Tips

Interview preparation tips for other job seekers - They didn't have any idea about what next round will be. I was told 2nd round will be about Golang database. Turned out to be kubernetes design round. That's okay but process is not streamline across candidates and questions level, feedback differ candidate to candidate.

Thay first didn't gave any feedback after 2 round for 10-15 days then said we are not going forward.
I don't think they consider level of questions asked in rounds are fair for all not. (Given that HLD round is open ended discussion ) Because had connected multiple people selected before sitting for interview.

You might get frustrated with randomness of their tech interview or maybe ghost job hosted by them
