I'd say your experience as a full stack software developer is basically irrelevant. At the end of the day, for a typical non-leadership engineering role, the hiring decision is not going to be based on your previous work experience. They are looking for strong algorithmic fundamentals and the ability to think outside the box (I've interviewed for both in the past).
I'm a university student who's found out a little too late that I might be interested in Quant. I have great marks and algorithmic foundations but my past experience has been in Full Stack/Web Dev, and I've struggled to get an interview from any of these firms (and I don't entirely blame them).
This seems to basically be true for any well paying ( > $200K) job at any of the better paying tech companies in the US. It’s all about the passing the algorithm coding interviews.
There a number of large, well funded “startups” that don’t do the traditional algorithm based interviews but still pay at or above that range.
As someone who's been involved in hiring for these companies - it's more accurate to say that for all but the most exceptional candidates, a decent score on the algorithms interview is necessary but not sufficient. I've seen fairly similar performances in technical interviews result in offers for mid-level (~$350k), senior (~$500k), or staff (~$700k) based on experience and the behavioral interview.
I can’t imagine how 10 years of experience as an SWE would be irrelevant for another SWE position, even if the industry is different.
Years of experience really counts for next to nothing. Two people with X years of experience could have vastly different skillsets and it genuinely signals next to nothing about how qualified they would be for this job.
Both roles involve highly technical interviews and then a 3 month probationary period that is quite challenging. If you have a lot of experience then I'd expect you to do well in the technical interview, although unfortunately in practice this doesn't end up being the case.
