Online Application & Screening

Deloitte’s online application and screening process is designed to be straightforward and efficient. You begin by submitting an online application through Deloitte’s career portal, where you’d need to create an ID. The application requires you to paste a plain-text version of your resume and, for campus hires, transcribe key academic details from your transcripts. DO include your location preferences as well.

Once your application is submitted, you’ll receive an automatic acknowledgment. The Talent Acquisition team then reviews your profile to assess your fit with the role’s key selection criteria. Give it around 2 weeks to get a call back, notifying you about the acceptance of your resume. A recruiter call could also be a part of the process, validating your responses and verifying your background.

Screening may also include an online assessment, which tests your verbal, numerical, and logical reasoning skills, as well as situational judgment and personality traits, depending on the role.

Online Assessment and First Technical Rounds

After making contact with an HR representative from the Deloitte Talent Acquisition team, you’ll be invited to an online assessment round to further evaluate your candidacy. This is typically an untimed round, but can stretch to even an hour if required. The round usually fragments into 3-4 subparts revolving around situational awareness, reasoning, coding, and personality assessment.

Group Case Study Discussion

After clearing the online assessment round, you’ll move to the Deloitte group case study discussion, a signature part of the interview process for consulting roles. Here, you’ll be grouped with 3–6 other candidates and given a real-world business case, often mirroring actual Deloitte client scenarios. You’ll have about 10 minutes to review the case materials, identifying key issues. The group then discusses the case for 20 minutes in front of Deloitte interviewers. The focus is on collaboration, structured problem-solving, and clear communication. Interviewers then engage the group in a Q&A for another 15–20 minutes, probing your reasoning and the group’s conclusions.

Technical or Functional Round With Senior Analyst/Manager

For more senior data engineers, software engineers, and similar roles, a functional round with technical hints may be conducted to filter out the best candidate. The technical or functional rounds with a hiring manager or partner at Deloitte are designed to assess both your domain expertise and your fit for the firm’s culture and client-facing roles. In these rounds, you can expect a mix of practical, scenario-based questions and technical deep-dives tailored to your experience and the role you’re applying for.

You’ll be asked to explain your thought process, justify your recommendations, and sometimes defend your answers when challenged. For consulting roles, you may also be presented with case problems.

Behavioral & Culture-Fit Interview

The behavioral and cultural fit rounds at Deloitte are designed to assess how well you align with the firm’s values, your interpersonal skills, and your ability to thrive in a team-oriented, client-facing environment. In these interviews, you’ll be asked to share real examples from your past experiences—using the STAR method (Situation, Task, Action, Result) is highly recommended to structure your answers clearly. Throughout the round, be authentic, focus on the positives, and use your responses to showcase your achievements and growth.

Case Study & Group Discussion Questions

In the Deloitte case study group discussions, you will encounter business scenarios that test your problem-solving, collaboration, and strategic thinking skills:

1. Would you consider adding a payment feature to Facebook Messenger is a good business decision?

To determine if adding a payment feature to Facebook Messenger is a good business decision, analyze the market demand for such a feature, assess the competitive landscape, and evaluate the potential for user engagement and monetization. Consider the technical feasibility, security implications, and alignment with Facebook’s strategic goals. Additionally, conduct user testing and gather feedback to understand user needs and preferences.

2. What metrics would you look at to determine the demand for rides at any point?

To determine the demand for rides, you would analyze metrics such as the number of ride requests, the time of day, and the geographical distribution of requests. Additionally, monitoring the average wait time for rides and the frequency of surge pricing can indicate high demand and low supply. Establishing a threshold for too much demand involves setting a limit on acceptable wait times or surge pricing levels, beyond which customer satisfaction may decline.

3. How would you design a system that offers college students recommendations to maximize the value of their education?

To design a system that maximizes the value of education for college students, you would need to analyze data on college programs, degrees, student finances, and alumni salary data. The system should evaluate the cost of education against potential earnings, factoring in financial aid, scholarships, and living expenses. By using predictive analytics and machine learning, the system can provide personalized recommendations that align with students’ financial situations and career goals.

4. How would you determine the overall impact of the integration on Prime Music subscriptions?

To determine the impact of Prime Music’s integration with Alexa devices on subscriptions, analyze subscription data before and after the integration. Consider metrics such as the number of new subscriptions, retention rates, and user engagement levels. Additionally, conduct surveys or gather user feedback to understand the qualitative impact of the integration.

5. How would you establish causal inference to measure the effect of curated playlists on engagement without A/B?

To measure the effect of curated playlists on user engagement without an A/B test, you can use observational data and causal inference techniques like Propensity Score Matching (PSM). This involves predicting the likelihood of user engagement with curated playlists using user-level features, calculating propensity scores, and matching users with similar scores to create a control group. By comparing engagement metrics between matched groups, you can estimate the causal effect of curated playlists. Additionally, Interrupted Time Series (ITS) analysis can be used to observe changes in engagement trends over time, further isolating the feature’s impact.

Leadership & Storytelling Questions

These questions focus on how you lead, communicate, and influence others through real experiences and impactful storytelling:

6. Talk about a time when you had trouble communicating with stakeholders. How were you able to overcome it?

This question assesses your ability to handle communication challenges. Be honest about the situation, describe how you addressed the issue, and explain what you learned to improve future interactions, such as tailoring presentations to the audience’s level of understanding.

7. What is your approach to resolving conflict with co-workers or external stakeholders, partially when you don’t really like them?

Provide an example of a conflict you resolved at work, focusing on your approach to finding a solution. Highlight your ability to maintain professionalism and work towards a resolution, even when personal feelings are involved.

8. Describe a time when you led a team through a challenging situation.

To answer this question, describe a specific challenging situation where you took on a leadership role. Explain the steps you took to guide your team, the strategies you implemented to overcome obstacles, and the positive outcome achieved through your leadership.

9. Share an example of how you used storytelling to drive change in an organization.

Using storytelling to drive change involves crafting a narrative that highlights the problem, the proposed solution, and the potential impact. By engaging stakeholders with a compelling story, you can effectively communicate the need for change and inspire action.

Behavioral & Culture-Fit Questions

Deloitte Q&A interviews often assess your values, interpersonal skills, and ability to adapt using clear examples structured in the STAR format:

10. What do you tell an interviewer when they ask you what your strengths and weaknesses are?

When discussing strengths, focus on what sets you apart and back it up with examples using the STAR method. For weaknesses, avoid listing insecurities and instead show how you recognize and manage them, possibly spinning them into strengths without appearing arrogant.

11. Tell me about a time when you exceeded expectations during a project. What did you do, and how did you accomplish it?

To answer this question, use the STAR method to describe a situation where you went beyond what was required. Highlight the additional value you provided, such as adding unexpected features or handling edge cases. Focus on the positive impact of your extra efforts on the project outcome.

12. How do you embody Deloitte’s core values in your work?

To embody Deloitte’s core values, integrate integrity, commitment to each other, and strength from cultural diversity into your daily work. Demonstrate these values through ethical decision-making, fostering a collaborative environment, and valuing diverse perspectives to drive innovation and client success.

13. Tell me about a time you worked on a diverse team and how you ensured inclusion.

This question examines your experience and approach to fostering inclusion in diverse teams. You should provide an example of a diverse team you worked with, explaining the strategies you used to ensure all team members felt included and valued, and the positive impact this had on the team’s performance.

Director & Partner-Level Questions

At the executive level, Deloitte interviewers explore how you align strategic priorities with client success and organizational leadership:

14. How do you balance business development with client delivery at the partner level?

Balancing business development with client delivery involves prioritizing tasks, delegating responsibilities, and maintaining clear communication with clients and team members. Focus on building strong relationships with clients while identifying new business opportunities and ensure that client needs are met without compromising the pursuit of new projects.

15. What metrics would you use to assess the success of a high-stakes Deloitte engagement?

To assess the success of a high-stakes Deloitte engagement, consider metrics such as client satisfaction, project delivery timelines, budget adherence, and the achievement of project objectives. Additionally, evaluate the engagement’s impact on client relationships and potential for future business opportunities. These metrics provide a comprehensive view of the engagement’s effectiveness and value to both Deloitte and the client.

16. How do you ensure alignment between Deloitte’s strategic objectives and your team’s day-to-day work?

Ensuring alignment between strategic objectives and daily work involves clear communication of goals and regular check-ins to track progress. By setting specific, measurable objectives and fostering a culture of accountability, teams can stay aligned with the broader organizational strategy.

Preparing for a Deloitte interview requires a strategic approach. Especially given the firm’s emphasis on group case study formats and data-driven communication. Its leniency towards core values also plays a critical part. In the group case discussions of Deloitte’s process, you are evaluated on participation and on the quality and clarity of your contributions. It’s important to approach these case study group discussion topics for Deloitte with a structured framework. Listen actively, synthesize information quickly, and ensure your input is purposeful. Contributing with inclusive dialogue and hovering over group perspectives can set you apart as a collaborative leader. This aligns with the company’s preference for candidates who enhance team performance rather than dominating the conversation.

When it comes to telling a story with data, the ability to integrate metrics into your answers is essential. Go beyond presenting numbers and craft a narrative that ties quantitative insights to the business problem at hand. Use clear visuals and focus on the ‘why’ behind the data, ensuring your story has a logical flow from challenge to solution to impact. For example, instead of listing KPIs, explain how a 15% reduction in supply chain was achieved through a specific initiative, and how those results fulfilled objectives. Practice your approach to these questions through our Mock Interviews and AI Interviewer.

Throughout the interview, map your responses to Deloitte’s core values—Impact and Integrity are central. Show how your actions have driven measurable change while upholding ethical standards. This could involve maintaining transparency with clients or fostering inclusivity in team settings. Demonstrating this alignment not only answers behavioral questions but also signals your fit with Deloitte’s culture of collaboration.
