In my experience it depends on the companies. Some are reasonabe/flexi and try to assess the potential of a candidate; other don't have a problem rejecting candidates for ludicrous reasons such as you used Xyz-lang up to version 1.23.4, we need somebody who masters at least 1.23.5. YMMW though

Some junior clojure positions: • Require zero clojure experience. • Others are designed for fresh graduates - with only the amount of knowledge a fresh CS grad is expected to have. • Others do require some clojure experience (sometimes just hobby and sometimes professional). It varies a lot company to company. If you want to get ahead - then I would focus on practicing writing Clojure using the core libraries. E.g. feel comformatable with using/manipulating/transforming/aggretgating clojure seqs, clojure maps, clojure vecs, clojure sets, strings etc. Ie be able ot solve basic interview questions. There are a lot of libraries in Clojure and companies all use different ones for Server/DB/Frontend etc - So I wouldn't spend time trying to learn third party libraries for a job as you can't predict which ones to learn. It is worth using/learning third party libraries though for your own personal projects as that's an interesting and enjoyable way to practice clojrue.

In general I think it's, "Will you pay for me to move to where your company is based?", i.e. pay for a moving company and possibly temporary rental

10 years ago one company provided a budget around 2k for relocation purposes. With a condition to return money back if I leave company earlier than in 2 years. Also they had a lawyer to handle visa/residence applications

They may just want the company to sponsor the VISA not even any extra money for moving costs.
