Behavioral Technical Coding

The process was really long. First, there was an online assessment with both behavioral and technical questions. The OA took a long time, about 1.5 to 2 hours. The 'technical' part mostly involved random math brain teasers and no actual coding. It felt like the OA was pointless and a waste of time. The one-way interview part was fine, though.

Technical Coding System Design Behavioral

The interview had a few steps. First, an online assessment with a SQL query and a coding problem. Then, a technical round where they asked about my projects, circuit breaker, docker, kuberentes, and a basic Java program. After that, an architecture round focused on my projects, experience, resilience, a scenario about a payment gateway, what makes a good or bad day for me, and questions about Kubernetes pods and containers. Finally, an HR round where they were nice and explained everything.

Confirmed questions1 question
  • Why is there only a single container allowed within a pod?

Technical Coding Behavioral

It was a walk-in interview with 5 rounds: MCQs, 2 technical rounds, 1 managerial round, and 1 HR round. It all happened in one day, but the final decision would be later. I cleared all rounds, and they discussed benefits, saying they'd inform me in a few days. However, the HR never called or responded to my emails. After 20 days, I managed to get their number and called, only to be told they weren't moving forward with my application, without any specific reason. It was a terrible interview process with no transparency, and the HR and hiring team were unprofessional. I wouldn't recommend joining this company.
