How to Get Hired as QA Engineer? Job Requirements and Tech Interview Prep Sources

Published in the Random group
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. How to Get Hired as QA Engineer? Job Requirements and Tech Interview Prep Sources - 1Same 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.

Learning sources to prepare for QA tech interview

Where to learn all of this professional QA knowledge and skills required to qualify for QA Engineer positions? Here is a selection of learning sources that you can use.

1. CodeGym

Over the years CodeGym has been the favorite coding skills learning source for thousands of our students. In fact, for many of them, CodeGym became the gateway to the career in tech as they never had any contact with the programming world prior to registering on CodeGym. Teaching the fundamentals of Java and software development in general, crucially important knowledge for QA Engineers to possess, CodeGym helps students to learn theory and acquire real practical coding skills in an entertaining and gamified way. We recommend you to check this piece for more details on how Junior coders and QA testers can benefit from using CodeGym.

2. Online courses

There is a great selection of various online courses focused on QA Engineering fundamentals as well as specific areas of knowledge in this profession. Here’s a list of solid online courses that are good for QA beginners.

3. YouTube guides

For those who like to consume the knowledge in a visual form, and most of us do because it is easier, here are a few YouTube video guides, tutorials, and informational videos for QA Engineering beginners.

4. Coding tests and Q&As

Finally, a great way to ensure you are trained and prepared for an actual interview would be practicing on resources with coding tests often used on technical interviews for QA Engineer positions, as well as going through a number of the best Q&A lists:
