JPMC | SWE III | Round 1 | Bangalore

I recently completed my first-round interview for a Java Developer position at JP Morgan Chase in Bangalore. The interview covered a range of topics, starting with several behavioral questions focused on my career motivations, problem-solving skills, and teamwork experiences. Following this, we delved into Java-specific technical questions, primarily revolving around concepts like synchronization, locking mechanisms, and the characteristics of ConcurrentHashMap and exceptions. The final segment of the interview involved a code review. I was presented with a class designed to manage account balances in a map, with methods for updating and retrieving balances. During the review, I suggested using ConcurrentHashMap for thread safety, which was acknowledged as correct, but I struggled to elaborate on its internal implementation details. My responses to the 'why JPMC' question and my recollection of the job description were not strong, as my current project work is primarily in C++. Given these factors, I don't expect to move forward in the interview process.
