Round 3 - Resume & Project Discussion

Duration: 45 minutes

In this round, the interviewer discussed my past projects at my current company, including the tech stack, my responsibilities, and my contributions. It was a conversational round, with occasional questions such as Docker vs. Kubernetes and SQL vs. NoSQL, based on the information provided on my resume.

Result: Hire

---

After clearing all three rounds, I was informed that only one final behavioral round remained. However, my application was put on hold, and I was left waiting for 75 days without any updates or a scheduled interview. Given the lack of communication and professionalism throughout this process, I eventually withdrew my application and clearly communicated my reasons to Avathon leadership team so they can fix this broken process!
