1. 086Why do you want to start your career on the buy side?Career and fitCorefirst roundMan GroupInvestments · London · 2022

   Say this

   Because the skill I want to build is judgement under accountability, and that is learned by holding positions, not by producing materials. The conventional route via banking teaches execution and stamina, which are useful, but it delays the thing I actually want to get good at by two or three years.

   Then walk it

   1. Acknowledge the standard path and why it exists: banking gives modelling reps, deal exposure and a strong network, and it is a safe default. I would rather trade that safety for earlier reps at the decision itself.
   2. Then the substantive argument: investing is a feedback-loop skill. You improve by making calls, recording them, being wrong and understanding why. Starting earlier means more cycles of that, and the cycles are slow, so the earlier the better.
   3. Then admit what you will miss and how you will cover it. The buy side gives fewer formal modelling reps, so I have built that deliberately, through my own models, a case competition, or a research seat, and I would keep doing it.
   4. Show you know what the seat involves rather than romanticising it: a lot of reading, a lot of maintenance on existing positions, few new ideas per year, and long periods of being wrong in public. That is the job, and I want it anyway.
   5. Give the evidence. Not 'I follow markets' but something specific: a portfolio with a written thesis per position, a mistake you documented, an investment club you ran and its actual results including the bad ones.
   6. And close on fit with this firm's style rather than the buy side in general. Systematic versus fundamental, multi-asset versus single asset, long-only versus long-short are very different jobs, and naming which you want, with a reason, is the part most candidates leave out.

   Where candidates lose it

   Framing it as avoiding banking hours, or claiming the buy side is more prestigious. Both are heard as immaturity. Also, 'why start on the buy side' invites the real concern, that you have not been trained. Pre-empt it by saying what training you will miss and how you have already covered it.

   Expect next

   • What will you lack by not doing two years in banking?
   • Systematic or fundamental, and why?
   • Tell me about a call you got wrong.
