The process took 2 days. I interviewed at Deloitte (Washington, DC) in Oct 2010
Interview
I submitted my resume and within the week I got an e-mail for a phone interview (which was also conducted within the week). The phone interview lasted about 15 minutes, and I only did fair, but a few days later I got offered to by flown to DC for the final interview. Two 30-45 minutes interviews (one case study one personality) and one shorter 15 minute interview. I left thinking I did decent, but didn't get the job. However, the entire process ended up being really fun and everyone was extremely nice and supportive--even though I was super-nervous.
Interview questions [1]
Question 1
I got caught off guard in a networking event and asked what I want to do in the future.
Interview process was not fair, they said they didn’t have enough interviewers so some of the candidates had to skip the technical portion. Unclear how they fairly judged us against candidates that got to do all 3 parts.
I applied through college or university. The process took 4 weeks. I interviewed at Deloitte (Atlanta, GA) in Oct 2015
Interview
Recruited at school through workshops and posters, dropped resume online, two-days of interviews (they cut about half the group between day one and two). Interviews were structured as 30 minute behavioral, 30 minute case study the first day, then 45 minutes of case and behavioral the second day. Also did lots of informational interviews with current Deloitte consultants (I think 4 or 5) after I dropped my resume and before I was told I had an interview, which is not explicitly stated as part of the interview process, but I think this helped a lot in getting an interview.
I applied online. The process took 4 months. I interviewed at Deloitte (Atlanta, GA) in Jun 2015
Interview
Submitted application online. Heard back from a recruiter couple weeks later and talked on the phone for 45 minutes about working in the public sector. Talked to another recruiter few weeks later about an opportunity in Atlanta, followed by a phone interview with a specialist on the team. Onsite interview in Atlanta: case interview with a senior manager, behavioral interview with a partner, behavioral interview on the phone with senior manager of the team. Received a contingency offer a month later. The contingency offer was based on whether or not the project will get funding from the client, which turned out it did not. Invited to talk to another team since the project I was "hired" for did not get the funding. Never heard back.
Overall, everyone I talked to was nice and professional. Deloitte is a big organization and has a lot of opportunities, but in order to be successful there, you need to network, network, and network.
Practice case interviews and use STAR technique for the behavioral interview. For the public sector, the cases are not your typical business cases, but the concepts are similar (improving efficiency, reducing cost, etc.)
They seem to gravitate towards individuals with entrepreneur spirit.
