Soft skills I don’t mind; grown up interviews I don’t mind. I have done freelancing for 30 years now and had 0 requests for balancing binary trees, time/space complexity of sorting algos; things that are often associated with interviews here on HN and things which I did, you know, in uni, for which, you know, I have a degree to prove I could do them and know what they are. They are generally 100% useless on modern jobs (I worked on specific embedded jobs I needed knowledge like it, but you can look that up as well). I just give my company’s (it is a 1-3 band gang depending on what the others are doing) portfolio and no one requests weird things like that.
Now soft skills are different and 2 of us are good at those and one of us is really bad; so we hire out based on the client, wishes and need for soft skills and a lot of communication overhead or not. And I agree that needs to be a match, however I cannot see how that requires 6-8 gruelling interviews spread over weeks instead of 15 minutes and a portfolio (which is how we get hired).
So yeah, I think OP would do better in a small collective of freelancers or even small consultancy company; I find it much easier to get into anywhere that way than the employee route.
