Entrevista
I applied online. The process took 2 weeks. I interviewed for Fidelity Investments (Boston, MA) in July 2020.
I had 3 online interviews (zoom):
1 with a principal engineer who asked me a parentheses matching coding problem. Asked a bit about my current role and responsibilities. (45 mins)
A week later, after getting through the initial technical round, I had two 1 hour back to back
coding sessions with a Senior Software and Principal Engineer and another one with a Senior Software and Software Engineer.
Both were purely technical,
In the first round, they asked me group of anagrams sorting problem.
In the second row, they asked me wrong way cow problem.
I was able to solve group anagram but my complexity is O(n)2. The interviewer was not really helpful or encouraging in anyway. He was a bit harsh.
I partially implemented the wrong way cow problem. (not enough time as 15min in 45mins were spent talking about my current role and responsibilities)

The worst part of the interview was the silence and the lack of any feedback afterward. The standard automated response was, “We’ve decided to move forward with other candidates.” Even though I completed two tasks in 45 minutes, and during the second interview, the manager himself said that all my answers were good.
