How long does the recruitment process take?

Once we have screened for candidates, had the informational interview and we’re ready to start with interviews, we aim to have each candidate’s recruitment process completed in 2 weeks.

What does the interview process entail?

Informational interview:

This is an introductory interview with someone from the team you’re likely to work with. You have an opportunity to ask questions about Castalia, the work environment and the kind of work you can expect to do. You will also be asked general questions about yourself and your professional education and experience. After this you decide if this is the job for you and if you want to go through our formal assessment process. At this point we also give you feedback on whether we think you’d likely be a good fit for the role.

Team interviews:

These interviews are designed to test your knowledge, based on the position you are applying for. Your understanding and application of finance and microeconomics will be tested if you are applying to be part of our team of analysts. All candidates will have an interview to discuss Castalia’s 6Cs, which is a discussion about our values and the types of candidates we’re looking to hire.

Final interview

The final interview will be with a member from our Senior Management. It will cover all elements mentioned above. Managers and above will have an additional interview with the CEO.

How can I prepare for the interviews?

We suggest that you read the following materials in preparation for the interviews. This is what we expect our team to know. If you’re unfamiliar with these concepts and the material, your application is unlikely to be successful.

Interview on microeconomics:

Basic Microeconomics, you’d want to brush up by reviewing an introductory microeconomic text book. The interview will typically cover the following areas:
- Supply and Demand, price formation, market equilibrium
- Utility maximization, profit maximization, equalization at the margin as a concept

- Calculating and comparing relevant financial ratios
Corporate finance – we suggest reviewing:
- How to value companies including DCFs and calculating present value, WACC and the CAPM model
