I applied online and received an email from a recruiter requesting to schedule a time for the first round of interviews.

The interviewer was friendly and asked some basic Java questions, along with questions about Hashtable collisions and chaining. They also presented a basic LeetCode algorithm problem and inquired about my background.

Later, I received an email with a coding question for the second round. The question was quite extensive for the timeframe provided. Although I completed it, I later received a rejection email stating that they didn't find a suitable position for my profile.

Java basics:

• Hashtable collisions and theory
• Memory management
• Question on Trees (cannot reveal the question, but you can do it easily if you know how to do pre-order or in-order traversal)
• A coding question, which is not an algorithm, but tests your Java knowledge.
