You should avoid Agencies if at possible.
Agencies consist mainly of chaff in my experience. I’ll give an example.
A few years back I received tonnes of interest from agency callers but only ended up getting a job after finding one myself.
Nowadays if I send my CV, I barely receive any interest. If I do the work and target specific ads I don’t receive any acknowledgement to my applications either. Even if the job is a blatant skills match, the result is a no response. Are agencies incredibly stupid or what?
