The interview process at Eastern Software Solutions (ESS) generally starts with resume shortlisting based on skills and academic background, followed by an online test that includes aptitude, technical MCQs, and basic coding questions in Java or Python. Shortlisted candidates then move to one or two technical interview rounds where they are evaluated on Core Java, OOPs concepts, collections, exception handling, SQL queries, frameworks like Spring Core, JDBC, and sometimes front-end basics such as HTML, CSS, JavaScript, or React.
