A principal engineer reached out to me via LinkedIn. I had a first interview with him, and he explained the role and the interviewing process. This process included several rounds with different team members and "live coding" tests to assess data analysis and visualization skills.

The first technical test was a "live coding" one to assess my SQL and JavaScript skills. The questions were basic, but I didn't perform quite well. After this, I received no feedback or follow-up from the recruiting principal engineer.

I believe that following up with candidates is key, especially after the effort they might have put into preparing for the interview.

Months later, I was contacted by another principal engineer for a similar position. The behavior was the same.

After these experiences, I would not like to apply again or work at Cisco.

In the first round:

Given a table(s), retrieve certain records (basic SELECT queries using filtering, aggregation, joins & formatting) and basic JavaScript array manipulation exercises.
