It was a 2-hour telephonic interview that covered my past experience, knowledge of algorithms, and coding questions.

This was followed by a couple of one-on-one telephonic interviews with two hiring managers.

One asked questions on TCP and congestion control; it was a technical round.

The second one asked on the same lines and gave a couple of small coding problems.

Overall, it was a good experience.

Asked one DP question, a variant of the Fibonacci series. Not that hard.

Asked a couple of string manipulation questions, followed by a few questions on regex matching and parsing YANG data files. The basic focus was on the approach.
