General questions about Object-Oriented Programming concepts. Questions on SOLID principles and high-level questions about design patterns. Questions on HTTP concepts and API testing, UI testing with different kinds of selectors (some of XPath and CSS). Finally, a coding challenge of basic to intermediate difficulty; that should take 10-20mins at most. There were also questions about experience in other areas, like mobile testing or performance testing (if you have it.)
