First-hand accounts from people who interviewed at Copper Digital.
Senior Software Engineer
First round, a Senior Backend Developer asked about my project and Node JS basics. Second round, the Project Manager asked about my project and the node modules I've used. The last round was a chat with the VP about my joining timeline.
- Tell me about CRSF Attacks.
- Can you explain Observables?
- What are Promises?
Software Engineer
I first got a call from a recruiter to set up an interview. After some back and forth calls and emails, we finally picked a date and time. The time got moved around a bit on the day, and the day itself was switched once, but then it went back to the original day. It seemed like they were juggling a bunch of interviews, but it didn't really bug me. As far as I know, there was only one recruiter involved. Once I got into the actual interview, all the questions were just tedious Java trivia. Even though Java is my go-to language, I was surprised by these silly questions that anyone could easily look up in a minute. What was really irritating was how the interviewer asked them, making me feel like my answers were off or ridiculous, even when they weren't, causing me to doubt myself. I never heard back after the interview, which is fine. Honestly, I wouldn't want to work at a place that judges your coding skills based on language trivia.
- Java doesn't support multiple inheritance, but you can implement multiple interfaces, which seems similar. Why is that? Were the original Java developers too lazy or incapable of implementing multiple inheritance?
- Can you explain the difference between an abstract class and an interface?
Software Engineer
There were 2 technical rounds, each about an hour long. These technical rounds depend on the specific role you're applying for. For instance, if someone is interviewing for a mobile app developer position, they can expect questions that are mid-level to hard-level and specific to their tech stack, along with some DSA questions.
- What are the different types of widgets available in Flutter?
