Yea that's the best, when they start out saying how they went over your profile and all the amazing things you've done in XXX language even though that's not listed on your profile at all!

That is why I have a NO JAVA Gmail template that tells the recruiter to learn to properly use their search engine https://www.lifehack.org/articles/technology/20-tips-use-goo... https://edu.gcfglobal.org/en/topics/googleapps/

Since it is a template it takes 20 - 30 seconds to respond

I sometimes get messages where they are searching for candidates with C# or Java experience, also telling me that I seem like a perfect candidate. I do have a little bit of that but for the past ten years I have only been working with embedded sw development (C and C++) so obviously they didn’t read very carefully. I have gotten good contact with good recruiters using LinkedIn as well though so it varies quite a lot.
