I want to receive updates regarding this question via email.

OC&C First Round Interviews

Hello, I have been invited for OC&C first round interviews and was wondering if anyone could share some information about it, a part from the fact that they will likely be asking market sizing questions. 

Also, does anyone know what the average rate for going onto the 2nd round (invited to 2nd round / people interviewed) is? 

Thank you in advance for your answers!

Hello!

Congrats on the interview, good way to kick off the year. 

Although I have not done the OC&C process myself, I know that is very similar to the classic structure in MBB and general consulting. 

Hence, you have 2 main workstreams ahead:

1. FIT INTERVIEW

The "Integrated FIT guide for MBB" has been recently published in PrepLounge´s shop (https://www.preplounge.com/en/shop/tests-2/integrated-fit-guide-for-mbb-34)

It provides an end-to-end preparation for all three MBB interviews, tackling each firms particularities and combining key concepts review and a hands-on methodology. Following the book, the candidate will prepare his/her stories by practicing with over 50 real questions and leveraging special frameworks and worksheets that guide step-by-step, developed by the author and her experience as a Master in Management professor and coach. Finally, as further guidance, the guide encompasses over 20 examples from real candidates.

You can see plenty of reviews from candidates who purchased it already.

Furthermore, you can find 2 free cases in the PrepL case regarding FIT preparation:

  • Intro and CV questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/introduction-and-cv-questions-fit-interview-preparation-200
  • Motivational questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/motivational-questions-fit-interview-preparation-201
  • Behavioural questions (ENTREPRENEURIAL DRIVE) >https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/behavioral-questions-entrepreneurial-drive-fit-interview-preparation-211

Feel free to PM me for disccount codes, since we still have some left from the launch! :)

2. BUSINESS CASE

You don´t have any more time to the classics of Viktor Cheng, "Case in point" book, etc. You need to get hands on asap:

1. Practice cases with partners asap, as many as you can do.Find experienced partners who can provide a good feedback

2. Practice your math skills, both in your cases and with ad hoc exercisess, such as:

1. ​Multiplying double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo

2. Leveraging math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

Furthermore, you should practice as much as you can, and ensure that you cover:

1. Profitability cases- basic profitability framework.

2. Idea generation cases: for any specif issue

3. Growth cases: market penetration, new product launch, product mix change, etc.

4. Pricing cases

5. M&A cases

6. Valuation cases

7. Value chain cases

Given you are under this much time contraint, consider working with a coach to foster speed and ensure you have a tailored plan to be very targeted. PM me interested!

Hope it helps!

Cheers,

Clara

Hi there,

Congratulations!

I imagine you've passed their online assessment screening phase?

In general, you should expect a similar process to the other consultancies (fit, case, possibly market sizing). That said, I would absolutely check with HR.

Furthermore, you will want to focus your preparation more on the areas the OC&C is known for (PE, M&A, CPG, TMT, Retail, etc).

Hello there!

First round interviews at OC&C typically include 2 30-minute case study interviews. 
You are right saying that there will likely be market sizing questions, though profitability could also be possible.

As for the rate it would be hard to predict due to the situation.

Hope it helps.

Hi,

- The first round tends to consist of "traditional" market sizing cases (e.g. P&L of a dentist). 

- I don't know exactly the rate for going to the 2nd round as we're also living a very particular situation at the moment.

Which office are you applying for? I might give you some specific tips depending on that as I've had some candidates who got into OC&C in the past.

Best,

Antonello
