DeciBio Consulting Interview Questions
& Process

It's been half a year since my interview and I started to write this. Things may be different now. Everyone during the interview process was super nice, and it was such a regret not being able to work with them. I wish this answer is helpful to people who are trying to get in there. I didn't get into the in-person stage of the interview, but just from the first few rounds, the HR, interviewer, and the panel who interviewed me are all super sweet and nice. If you are reading this message to prepare for the interview, I wish you the best and hope this would help. The first round is a HireVue style answering behavioral questions and a short market sizing question, and another heuristic question like coming up with something. The second round of the interview was a case study (very simple and easy, not a lot of calculation, and the interviewer was super nice). The third round was where I failed. You are asked to make a deck about a marketing entry style question with provided information. It's really a time crunch, so try not to put every piece of information on the deck. Be selective. If I were ever offered to do it again (actually this was my second try but I still failed :(, there are a few things that I would say do it differently: 1. Do not try to make too many slides (I would say I should have made only 6 slides instead of 16) - you can condense the information to make the logic + evidence clear in a single slide, rather than jumping between here or there between slides. 2. Do not spend too much time on aligning the textbox or making things pretty. Color and bold letters work for presentation, but a pretty slide is not the core of this interview. Everyone understands that you only have a few hours. 3. If possible, try to have a few hidden slides. It shows the intellectual maturity that you are prepared for potential questions (thinking a step ahead). 4. Ask questions to your interview guides. They are analysts/associates who will be working with you for the next few hours. They've also gone through this. They know the best. Take the chance to ask them questions when you can. I didn't ask any questions, which I regretted. 5. Thank you letter. I didn't send the thank you letter but I really want to say this is one of (if not the most) the best interview process I ever had. They are very encouraging and there is absolutely no need to be nervous during the process. Also even the rejection letter is not a template which they just insert your name in the beginning. I really like the culture and wish I've done a better job.

So, I had a few rounds of interviews. The first one was this HireVue thing, like a virtual interview. It started with some personality questions, like, 'What would you do if you weren't in this field?' and 'Tell me something surprising about you.' Then it moved into a case study that I had to talk through to the camera. I think the second round was just a chat with HR, but honestly, I can't recall perfectly. The second to last round involved a logistical case study. No heavy math, mostly just explaining how AI will change the industry, talking about potential growth, and any worries. The very last round was a case presentation. I had to put together a presentation deck and then present it to the hiring team. They asked a few follow-up questions, but it wasn't heavy on consulting math or anything.

First, I had to do this online prerecorded interview. It started with a quick intro to the company, then a series of prerecorded questions came up one by one. After each question, there was a short countdown timer before it started recording my answer. I had a set amount of time to answer and couldn't pause or re-record, but they said I could take a moment on camera to gather my thoughts before speaking. At the very end, there was extra time to record anything else, like if I got cut off on a previous question.

So, the first round was a prerecorded interview. It wasn't your typical behavioral questions, but more like 'what/who is your alter ego' and 'what's something about you that surprises people'. Then there was this multi-step case study where they asked about pricing, marketing, and the customer base, and they gave a lot of creative freedom.
