      Java Software Engineer Interview

      3 Jul 2025
      Anonymous interview candidate
      No offer
      Positive experience
      Average interview

      Application

      I applied online. I interviewed at ioet in Jul 2025

      Interview

      I had 2 interviews (Jul 2025) 1) HR interview. The interviewer was very nice! He asked about my years of experience, previous jobs, and the usual stuff. Asked for my salary expectation and if it was negotiable. Half of this was in spanish as he already listened enough to know my level of english. 2) Technical interview. This one was about core concepts of OOP, data structures, time complexity, frameworks, ORMs, REST APIs, etc. Also had a question to sketch a basic API with the verbs and URIs for each CRUD operation according to the scenario. Lastly I had a coding exercise which I failed to complete on time; the only rule was I couldn't use any genAI, but I could google almost anything I wanted Both interviewers were very nice to speak with.

      Interview questions [1]

      Question 1

      Give me an example of when to use an interface. What's the time complexity of searching for an element in an unsorted list? What's the time complexity of searching for an element in a Hash map when you know the key of that element? How does an ORM work?
