I gave up on the chartered route
1) My application was "lost" for several months, during which time the rules changed and I had to re-apply.
2) I was charged am additional fee to be told that my BSc was not an MSc and was not on the "approved list" - it was a joint honours degree in computing and electronics from one of the top universities in the country.
3) My contribution to two de facto standards (MISRA C and C++) was considered "irrelevant and of only academic interest".
However, I still call myself an embedded systems engineer and think that my 30+ years of experience may just count for something.
