The process took 3 weeks. I interviewed at Fidessa (London, England) in Feb 2011
Interview
Fairly easy online aptitude test - not technical, looking at spatial perception etc.
Then a 2-3 week wait & eventually a fairly lengthy 1:1 interview - a technical skills test (knowledge of the language, + some algorithmic stuff) followed by a relatively informal chat with some of the development team.
People very nice, professional and down to earth. Office itself seemed to have a slightly sterile atmosphere although I only saw a part of it.
Interview questions [1]
Question 1
Had to write a C++ function to solve a particular problem (bit like a college assignment-type question).
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.
