This comment describes a real problem for senior engineers who want to explore a new domain. It is impractical for someone with 10+ years of experience to work as an entry level engineer. What other options exist besides completing online course to get experience in that domain? This is not specific to ML/AI roles. The same problem applies to anyone who wants to explore any of these domains - SRE, DataEng, Backend, Frontend. Personally, I am a backend engineer who wants to get into ML Infra roles. My current plan is to do these online courses, and hopefully transfer internally to a team working in this area. Only after having real industry experience in this area, look for more opportunities elsewhere. I am genuinely curious if anyone has better ideas for people in my situation.
