Glassdoor users rated their interview experience at QuantSpark as 100% positive with a difficulty rating score of 4 out of 5 (where 5 is the highest level of difficulty). Candidates interviewing for HR-Executive and rated their interviews as the hardest, whereas interviews for HR-Executive and roles were rated as the easiest.
Quite straightforward, talent call, code test, panel interview/case study. Most people seemed very friendly.
They rated me much more junior than every other process I was in, just not the right fit I don’t think.
The process was very quick, which is refreshing vs some 3 month processes I’ve been in.
Company reviews seem pretty awful, get the impression that this is coming from the top as the junior and mid level employees were all really nice.
I applied online. The process took 2 weeks. I interviewed at QuantSpark in Sept 2025
Interview
Had one interviewer with an Ops Manager at first stage for a Talent role. Had an enjoyable conversation but unfortunately was completely ghosted even after sending a follow up email.
I applied through a staffing agency. The process took 2 weeks. I interviewed at QuantSpark (London, England) in Oct 2025
Interview
Very poor and disorganised. Keep changing dates they ask for interviews. Dishonest representation about themselves. Now they are trying to be an AI bandwagon groupie. Now we know why existing employees and past employees give it 2.9.
