Very well structured with multiple rigorous rounds of interviews. Interviews ranged from group to panel to 2 on 1 interviews. Group Interviews were run first and the final interview was 2 on 1.
I applied online. I interviewed at Deloitte (Zaventem) in Mar 2026
Interview
1. Screening Call
2. Business Case
3. Super day (HR interview, Manager interview and Partner Interview all in one day)
It was quite fast, all of it took 1 month.
It was very unclear at the end, they weren't clear as to why they couldn't give me an offer nor give me a refusal. I ended up ending the process myself.
Interview questions [1]
Question 1
Why deloitte ?
Explain to me what's OOP programming ?

Didn't interview, but did an aptitude assessment that consisted mostly of case-study questions. They would give large blocks of information in fake research reports, and ask questions requiring you to sift through the reports and apply fairly simple mathematical operations.
