they do lots of algorithmic execution. They have a big back office support team for that stuff.
If I was a trader handling flow, you're telling me I would get hired by a bank to work BO or MO? That makes no sense. Either they would hire me as a trader or they wouldn't.
Being a trader for a proprietary trading firm does not have anything to do with being a trader for an investment bank.In the second one, you do a completely different job...you play a totally different game since you are negotiating the price...you are literally making it.
However, let's assume you want to be a prop trader at a bulge bracket:
Have you ever seen prop traders in big banks?
have you ever noticed that the majority of them is
at least 35 with than 10 years of experience?
look at their resumes and you will immediately realise they have many MO jobs in their previous positions (risk management, quantitative analysis,etc). there is no way a big bank is going to give you millions to trade if you dont know EXACTLY what you are doing and you get there after years of experience and knowledge.
Real life is different from Uni...you can get a job even if you are a complete idiot as long as your parents gave you enough money to do a master at Harvard or Oxford but landing a prop trader job in a bulge bracket means you have to make money and they do not really care who you are or where you got your degree from. you make money:good.you do not make money:bye bye. end of the story
If you want a job as a prop trader in a bank you'd better off going through a fund first and then go for a bank. An execution trader is just something you can begin with that's why they hire even fresh graduates: it is a mechanical job.
Piece of advice: get this job, learn as mush as you can, get some experience and THEN move somewhere else.
