I haven’t done the course but Erlang Solutions has been around for almost as long as Erlang itself, so in the BEAM world there’s probably nothing that comes close in terms of certification credibility

Has anyone here taken the certification recently?

I did… many years ago.

What was your experience like (difficulty level, format, preparation resources)?

It was not extremely difficult but it did require some serious OTP knolwedge.

Was the certification valuable for your career or current job role?

Yeah. It definitely helped me get my second Erlang job (the first one was the one where I learned Erlang ).

Any recommended study material or tips you’d like to share?
