Since 1997, I’ve certified and re-certified covering over 60 exams, but that was in the fields of data networks, service management, project management and service architecture. In these fields, it’s expected; it doesn’t seem to be the case in coding, unless they are for vendor systems and services, such as AWS, Microsoft. Anything ‘vendor’ related, then certifications can be a prerequisite for interviews .
I’ve conducted lots of interviews, and self-developers are typically the ones I’ve hired, because it demonstrates a mindset. I’m 52, and I’m coding for interest at the moment, but my intention is to start building websites for my local community in Spain, something I used to do in the UK. Your best CV will be the work that demonstrably reveals your abilities.
