So there were 4 rounds in total. The first round was an online test with MCQs covering Java, React, basic math, and development topics. The second round was a technical interview focusing on DBMS, SQL queries, DSA questions like linked lists, and Java coding. The third round involved discussing new Java concepts, questions about my hobbies, and a mix of other things. Finally, there was an HR round.

So, the interview process started with some DSA questions, focusing on strings and arrays at a medium level. Then there was an interview covering questions about my resume and projects, my programming language knowledge, static versus non-static concepts, and my approach to projects. They also threw in some MCQs and a few behavioral questions. That was pretty much it.

Technical Behavioral

My interview with NovaTech Solutions was a mixed bag. It had two main parts: first, I talked with the recruiter, and then I had a technical interview. The recruiter was nice and explained the job and company vibe well, so that part was pretty easy. The technical interview was tougher than I thought, with some abstract questions that didn't really match the job description. The interviewers knew their stuff and were professional, but some questions felt too theoretical and not very practical. A big drawback was the long wait for feedback. Even though the interview seemed to go okay, I had to ask several times for an update. Also, they only talked about salary right at the end, which made it hard to know if it was even a good fit financially from the start. NovaTech seems like a decent company, but their hiring process could be better with clearer communication and interview questions that actually relate to the job.
