I'm in my second semester as junior in college, and until recently, I've been on the pre-med track. Long story short, I realized that I wasn't planning on going to medical school because of my passion, but because it would make others (my parents) happy. Thus, up until now, all of my experience has been medically-related: volunteering, clubs, pre-med classes, etc.
Recently, I've learned about SQA engineering, and from what I've learned so far, it's seems like an interesting field to work in that appeals to me. I'm still not sure if I'm dead-set on the field, but it certainly is an option I'm keeping in mind. That said, I took an AP Computer Science class my senior year of high school, and have intermediate understanding in HTML, and beginner's in CSS. That's as far as it goes with my computer science experience. I would consider changing my major from Biology to CompSci, but I'm already so far into my requirement courses that it would throwing all of my work away.
So, my question is: if I were to become an entry-level SQA engineer, how would I go about doing so? I know of some people who had no experience like me, and still got a job with good pay. I know I need to get certification, but my main concern is how I would size-up to those with computer science majors, and what can I do to better my chances at getting hired? And as a minor sidenote: do I need to do anything special (certification-wise) to work abroad, such as in the UK?
