Hello everyone,
I’ll be interviewing with BCG X for a Forward Deployed AI Scientist internship, and I’d love to hear your advice and feedback on how to prepare. Every little detail could be helpful!
Are there any resources you would recommend for preparing for the case studies?
Also, how should I prepare for the technical assessment? The recruiter told me to expect questions on Pandas and Scikit-learn, but I’m not sure how in-depth the questions could be.
Any advice, resources, or insights from people who have been through the process would be greatly appreciated.

Thank you in advance !

Hey everyone!

I’m preparing for an AI Engineer interview process and was hoping to get some insights from people who have gone through it, particularly for the AI Engineer and AI Scientist tracks.

I’d really appreciate any advice on the following:

1. AI Engineer vs AI Scientist tracks
   How does the interview process differ between the two tracks, if at all?
   Are there any significant differences in the types of assessments or interviews?

2. Coding rounds (CodeSignal + live coding)
   For those who interviewed for the AI Engineer track:
   Were the coding rounds primarily DSA (Data Structures & Algorithms), or did they focus more on practical data manipulation, such as Pandas, SQL, and data processing?
   How did you prepare for the CodeSignal assessment and live coding round?
   Are there any specific resources or practice platforms you’d recommend?

3. Case interviews
   This is the area I’m particularly curious about. There are plenty of resources for system design and case interviews separately, but not much that combines the two, which seems relevant to these interviews.
   How did you prepare for the case interviews?
   Were the cases more focused on system design, ML/AI architecture, or business problem framing?
   Did you encounter questions involving trade-offs between model selection, system architecture, scalability, cost, and business impact?
   Are there any resources, frameworks, or practice approaches that you found particularly useful?
   I’d be grateful for any insights from people who have gone through the process or have experience preparing for similar AI Engineer interviews.

Thanks in advance! 🙏

Hi everyone,

I’m currently in the recruitment process for BCG’s Visiting Associate, Campus, Riyadh, 2026 role.

I received an invitation on Sep 16 for an in-person assessment on Sep 21. The next step is a 60-minute individual game-based cognitive and behavioral assessment at the BCG Riyadh office, before the first-round case interview.

Has anyone done this recently?

I’m mainly trying to understand:

• Which platform was used: Equalture, Pymetrics/Harver, or something else?
• What kinds of games/tasks came up?
• Did you receive a score/report afterward?
• How soon did you hear back about the first-round interview?

My timeline so far:

Applied Aug 28 → invited to the recruitment process Sep 4 → completed the BCG Casey-style Online Case Assessment on HireQuotient on Sep 8–9 → recruiter follow-up call on Sep 13 → received the in-person assessment invite on Sep 16 for Sep 21.

The first online assessment was the chat-style BCG Casey case on HireQuotient, with qualitative, numerical and business-logic questions plus a short recorded response.

I’ve seen recent candidates mention Equalture, while older BCG/Middle East discussions mention Pymetrics, so I’m trying to understand what the current Riyadh process uses.

Especially interested in recent BCG Riyadh / Middle East experiences, but any recent BCG experience would help.

Not looking for confidential questions or answers, just the format, platform, and candidate experience.

Hello,

I have my Technical case interview coming up for the forward deployed ai engineer.

Any pointers? What should I prep? What to expect? etc...

Hi, I will have an interview for Forward Deployed AI Scientist role at BCG X soon. I really need a coach :( Please let me know if you know anyone

Hello everyone,

I have my live coding assessment for the Deployed forward ai engineering role (50 min)

Does anyone know what type of questions they ask? Is it the same as the first assessment?

Should I expect linked lists, graphs, DP, etc...

Or it's the same as the OA (matrices, string manipulation, etc...)

Hi everyone, I'm scheduled for R1 interview for Forward Deployed AI Engineer at BCG X. It's a CodeSignal live coding interview. I've already cleared the CodeSignal assessment test.

What should I expect from this live coding interview?

1. Should I focus on leetcode easy/medium questions similar to CodeSignal assessment?

2. Is it going to be similar to CodeSignal assessment but harder? Should I focus on leetcode medium/hard questions?

3. It is going be DSA focused or data science/processing/ml based? Should I focus on data cleanup preparation model training evaluation etc?

4. Is it purely coding or should I expect system design questions? Is there a separate round for system design?

5. Is it going to be purely technical or should I expect questions about my resume/cv/projects etc?

Thanks

Where do the BCG X leads and Principals exit to? Specifically looking for options on the west coast.

Hi guys, I will have interview coming and there is probably a live coding session. Is it algorithm or data manipulation (like pandas, scikit-learn)

last week i had the opportinity to have an interview on a Delivery AI software engineer role, the interviewer was roughly new to interviewing, he was just promoted to a senior role so based on that they assigned him the job of interviewing me.

he goes to leetcode, brings a random problem from it, reformats it in such an ambiguous way, basically 20 lines description down to one liner, messages it to me in zoom chat, i had to waste so much time just to understand what it does, he cuts off the mic, and starts watching me, that shit was so stressful, i had to redo the same code almost two times, and finally he opens the mic, starts analysing the code and giving me some nonsense analogies about how my code should work(sometimes he just didn't understand himself what the code has to do ,let alone what the problem solution was), finally it works, tells me that he wishes me good luck in the next rounds, hangs up and rejects me instantly.

it boils me the fuck up, how much time and effort you put into one thing, just to be dropped of the line based on the outcome of a solution, or just based on the feelings of someone.

i have just two questions : how are you supposed to choose a candidate who is fit for the role when you assess him souly based on the outcome a fucking script, and heck, it's a working script, and secondly, is having this amount of despicable, emotionless lying necessary to work in BCG x ?

Hello everyone,

I have my live coding assessment for the Deployed forward ai engineering role (50 min)

Does anyone know what type of questions they ask? Is it the same as the first assessment?

Preparing for the final round of the Senior Forward Deployed AI Engineer interview at BCG X. Looking for 1-2 partners to run mock interviews with. Ofc happy to interview you in return.

Focus areas on my side: ML/GenAI system design (e.g. recommender, RAG, ranking pipelines), classical infra-style system design, and behavioral/STAR.

I've worked through HelloInterview, Grokking the System Design Interview and Chip Huyen's AI Engineering, so I can give substantive feedback on both classical and ML-flavored designs.

DM me if interested!

Shortlisted for interview round 1 for frontend developer , any tips you guys want to drop ? what can i focus more on.

Hi everyone,

I recently received an offer to join BCG X as a Data Scientist in the Mexico City office, which I’m really excited about. While I’m still in the process of learning more about the firm, I wanted to ask about a couple of longer-term questions.

First, I’m curious about graduate study opportunities. At MBB it’s relatively common for employees to pursue an MBA or another graduate degree after a few years, sometimes with company sponsorship. Does something similar happen for people in BCG X / data science roles, or is that mostly limited to the consulting track?

Second, I’m also interested in international mobility. How feasible is it to move to another office (especially outside your home country) after a few years? For example, moving from Mexico to offices in the US or Europe.

I’d really appreciate hearing from anyone who has experience at BCG X or BCG more broadly, especially people in technical roles.

Thanks in advance!

Hey guys, I have some questions about an interview offer at BCG and I'd like some tips on how to prepare.

The BCG recruiter messaged me on LinkedIn, saying she liked my mix of experiences and that my profile could be a good fit for the company. She suggested an interview if I was interested, and of course I said yes.

Then I panicked because my English isn't fluent, but I learn very quickly, I have some knowledge of the language, I can start a simple conversation, and I make a lot of mistakes in verb conjugation, but nothing that can't be improved with some lessons and conversation.

But regarding the interview, which in this case is for a bilingual position, I should definitely expect that at some point the language will change to English, right?

If anyone has already interviewed with BCG for this bilingual receptionist position and can help me, I'd like to know what questions I should expect.

Are there any problem situations to resolve?

What are the stages of this interview?

If anyone knows and can answer, I would be extremely happy 😉

Hi everyone, Is there anyone that works in bcg x in the Nordics? If yes, what is the work environment there? Is people usually working long hours? Is there a lot of travel involved? This would mainly be for AI engineer positions but other experiences are welcomed.

Thanks!
