They sent me a web automation task. I completed it above and beyond the requirements. They passed me to the next stage. In the second stage, the QA manager and a (so-called) Senior automation engineer interviewed me. I answered almost all the questions of the QA manager. The Automation engineer wanted me to automate a further scenario to the one that I automated in the first stage. I automated her request. She asked me how I would handle a situation requiring collection manipulation. Typically, a junior tester might use nested for loops to achieve that, which would require more than 10 lines of code. I, however, said I would use Stream, which does the same job in one line. She reacted like she heard the Stream first time in her life. She thanked me and we finished the interview. I'm not sure if she knows what Stream is :D
