I got shortlisted for an interview at CISCO for SDE position and just finished my interview 30 min before wiriting this post.

Background- 3+ yoe, Btech ECE

First round was a phone screen round with the Hiring manager at Cisco. It was a resume-based deep dive. I was asked to deeply explain about the products I have worked on and the tech stack they use. My familiarity with the job requirement\'s tech and some overview of the team, work-culture and product I interviewd for.

There will be two coding rounds:
1. Purely coding round
2. Coding + design round

I have only appeared for round 1. The interview started with the discussion on my resume and more deep-dive to resume based projects and tech. I was asked some theory questions too, like-
- What is the difference between SSH and TLS.
- Inner join vs Outer join in databases.
- Transactions and its uses in databased (explained ACID properties here).

The coding question I was asked was a Leetcode medium difficulty question. I am posting the question I was asked below-

I am moving forward to the second round of interview too. I will update this post later.

[Update]

Round 2 Coding round

This was again a coding round and focussed more on Golang(since its a go dev role) syntax, goroutines, unbuffered and buffered channels, mutex, waitgroups, etc.
was asked to write a Fibonacci program in go using channels and go routines. Was asked a few more resume-based questions as well.

Round 3 Managerial round
Discussions about project, tech stack, daily requirements and role expections.

The feedback was positive, I am waiting to receive an offer.
