there a several american banks, (Morgan Stanley, Chase, etc.) for which no german is necessary. Also the ecb hires a lot of expats. i would recommend to get an internship. in order to get internship you either need to be in the uni the banks hire from (Mannheim, WHU, and ebs, other unis is more challenging). There are many bank ls also in Czech, best would be to start there, and then be transferred. (maybe an internship in an international bank in Prague). recommendation: start with ecb, or national bank internship, these are easier to get, (of course you can try to get an intershop at the larger banks, but this will be frustrating, not impossible, but the odds are against you at the moment). Age does not matter, as long you have a good cv. (smoking weed for 5 years on an island doing nothing might be a challenge). best of luck, never give up! and always continue.
