Nothing too difficult about the technical questions, I came from a public school in CA near the start of my JR year, and by the end of the year every type of question that was asked was covered in class. They don't look for the absolute best answer, as long as it's not overly complicated.
Initial round was a online mcq round comprising of 15 technical questions.Duration was 30 minutes. Unfortunately kicked out of first round
One or two design questions. Remaining all were on DS and algo e.g. BST, linked lists, practical implementation of these concepts. Some were on the OS basics.
Every thing was basics. I screwed it up
What are the main interfaces in the Java Collections Framework? What are the differences between HashSet and TreeSet? What is the difference between HashMap and Hashtable? Explain the difference between Comparator and Comparable. How do you iterate over a List in Java? What is the difference between Queue and Deque? What is the difference between ArrayList and Vector? How does a ConcurrentHashMap work?
Technically speaking, for all the tools I would have to use in the job, they questioned me about my experience with them and have made some tricky questions around it to make sure I really knew it.
oops concepts, testing scenario, db migration, Java program on validating brackets and code review. scenario based testing strategy.
Questions were related to java and some testing concepts along with projects on my resume. There were also some algorithm based questions and riddles.
1st round questions: Discussion about my roles and responsibilities in my current company Overview of automation framework Linux commands, server connecting command Problem solving question to find unique characters out of a string Java question (difference between JVM,JRE,JDK) Apart from this there were few more questions. 2nd round: The discussion was heavily focused on syntax-level details — for example, being asked to write specific code that is typically referenced or reused from existing test frameworks or classes. Additionally, there were questions about exact syntax from work I had done around two years ago, which may not fully reflect current skills or how automation engineers approach problem-solving today.
