Investment Banking Mock Interview

“I like how julian creates questions based on our resumes. The interview feels more personal and similar to questions an interviewer might ask. I also appreciate how he ramps up the difficulty of his question. It started off easy and a lot harder. However, sometimes I don't feel like I'm being tested on the correct stuff. For example, the content I am learning from the mergers and inquisitions 400 question guide isn't being tested at all. But it makes sense since you will not be tested over that.”

Investment Banking Mock Coffee Chat

“Kitty was extremely helpful and generous in sharing her experience. She gave me a clear overview of the Goldman Sachs recruitment process, including the HireVue, Superday, behavioural questions, technical preparation and commercial-awareness expectations. I particularly valued her honest description of the culture and day-to-day work during her internship, as well as her practical advice on networking and using WSO effectively. She listened carefully to my questions and gave detailed, relevant answers rather than generic advice. Her guidance on speaking naturally, adapting behavioural stories to the exact question and prioritising understanding over memorisation will be especially useful for my upcoming interviews. I left the session with a much clearer preparation strategy and would strongly recommend her to other students.”
