One of many great things about having a professional career in tech and software development is the abundance of career paths and specialization options that you have. As we mentioned recently when analysing how long an average developer’s career typically lasts, if you are tired from being a programmer you can always switch to analytical, customer-oriented, product-focused and other types of roles where your coding skills will still be applicable and valued. Same is true for the opposite career switch direction. We know that many people already working in various other tech-related positions are combining them with learning programming languages and plan to either switch to being developers or enrich their skill set for current roles. The data from CodeGym’s recent user community survey shows that around 30% of our students already work in tech and are looking to extend their knowledge. Quality Assurance (QA) Engineer is a good example of an IT position with a potential to be a fully fledged career path that is in many ways parallel to Software Developer’s path. QA Engineer is also an in-demand position that is at the same time relatively accessible for beginners to grasp. Which makes it quite a good starting point for Junior programmers and those who are looking to get their first professional experience in software development. How to get a QA Engineer job is exactly what we are going to focus on today. We already talked about what you need to become an Android Developer in a previous piece, now it’s QA Engineer’s turn.
