As everyone here suggested they asked the airport gates problem. (It's similar to Meeting Rooms II problem in Leetcode)
The second problem was Given a string consisting of uppercase and lowercase letters, remove the matching pairs (Aa, Bb, etc) until there are no matching pairs within the string. (Similar to Matching Parenthesis Stack problem)
2. One way interview (3 questions)
Why Fidessa, Favourite Language, What can you bring to table or something like that!
3. Online Technical discussion
Leetcode String compression
Leetcode K-diff pairs in an Array
Given an index of a song in an array and a target song, what is the minimum no of steps to reach that song. You can traverse forward and backward in that playlist.
Given strings, find the unique string and return them in sorted lexicographic order
4.Skype interview
As stuff about experience and your fav project, questions about TCP , UDP advantages of UDP over TCP. How to find missing packet in UDP and so on. They eventually rejected me inspite of doing well in all interviews. They are looking for people with C++, Unix and Networking background and it doesn't matter if you're a good problem solver or if you have good communication skills.
I applied online. The process took 2 weeks. I interviewed at Fidessa (New York, NY) in Jul 2022
Interview
Easy C++ test then a 1:1 zoom call with one of the managers (Doug). He was super disrespectful and arrogant, questioning the technical parts of my previous job as if he knew better. Got ghosted by the company after.
I applied online. I interviewed at Fidessa (Jersey City, NJ) in Jan 2020
Interview
The process includes the online coding section and the phone interview process. The phone interview is mainly about the algorithm with Leetcode easy level questions. The questions are required written in C++.
The interviewer did not have communications.
Applied online, and then sent an OA, but I didn't pass. The OA is about two coding questions for 90 min. It was a positive experience that you know what you need to practice.
