Firstly call from HR and then 1 panel interview. Mostly questions about experience and previous projects with focus on system design (how would you solve x, what is your experience with y).
Interview questions [1]
Question 1
Gitflow, storage, cloud, logging and monitoring, languages.
I applied online. The process took 2 weeks. I interviewed at ADTRAN (Bengaluru) in Oct 2024
Interview
Smooth process. Guidance was given at every stage.
There were 5 rounds in total. 2 Tech rounds were most important and lengthy ones.
Overall the interviews focused on Java basics, dsa, multithreading and HLD and DLD questions. HLD was based on the project which you worked on. DLD questions on some requirement was asked to implement end to end. So practice design mostly.
I applied through a staffing agency. The process took 3 days. I interviewed at ADTRAN (Noida) in Mar 2024
Interview
Got call via consultancy for REMOTE opportunity. There were 3 rounds of interview. I cleared 2 of them. 3rd round too went well. But in 3rd round, I got to know that this job requires individual to be in Bangalore for first 8-10 months. Atleast they should mention this fact in their job description. Wasted 3 days of my time. Totally useless job description and useless team to not communicate in advance.
I denied in last round saying that job description clearly mentions REMOTE and that's why I opted for lower salary. Else, If I would have known that they want me to work from Bangalore for 8-10 months, wouldn't I have told salary expectation accordingly.
