Real, anonymous reports from people who interviewed for Business Analyst at Deloitte, newest first and distilled into what to expect across the loop.
My process started with an online assessment for the Deloitte analyst track. The problem was a programming-style prompt about palindromes: I had to determine the 7th nearest palindrome given an integer N (with N up to 10^9). The task felt very algorithmic, and I leaned on an approach described around precomputation plus a search strategy rather than trying to brute-force from scratch.
What stood out for me was how the process was split into multiple phases delivered by email. I kept getting assessments to complete before actually speaking to people, and while the early communication covered logistics and my background, the HR part mostly framed my experience.
Candidates typically start with an online assessment focused on programming challenges, such as finding palindromes or basic coding tasks, which require clear logic and attention to detail. It's crucial to prepare for algorithmic thinking and edge cases.
The technical interviews often include Java-focused questions, SQL queries, and practical coding tasks, emphasizing fundamentals and problem-solving skills. Candidates should be ready to explain their thought processes clearly and handle scenario-based questions.
Behavioral and HR rounds focus on motivation, fit, and personal experiences, with straightforward questions about career goals and past projects. Candidates should prepare to articulate their background and how it aligns with the company's values.
The interview process is structured into multiple phases, often with back-to-back interviews, which can feel intense but also efficient. Candidates should expect a quick turnaround in communication and decisions after completing the interviews.
Some candidates may encounter group case interviews, which assess collaboration and individual contributions under observation. It's important to be prepared for both teamwork dynamics and case analysis.
Several candidates reported issues with communication and scheduling, leading to confusion and frustration during the process. It's advisable to maintain clear communication with HR and be proactive in addressing any logistical concerns.
