Candidates describe the Plastipak Software Engineer interview as broad rather than brutally hard. The most common thread is a Java backend and SQL focus. Reports mention Java 8 and core Java, the Stream API, how HashMap handles collisions and resizing, Spring Boot annotations, dependency injection, @Transactional, microservices and communication between APIs. SQL questions ranged from joins and scenario-based queries to SQL injection and triggers. Candidates also describe stack variations, including .NET with React in one report and Java with Angular in another, so check the posting to see which stack your version of the role uses.
Project questions come up repeatedly. Several candidates say interviewers built questions from resume items and expected clear explanations of what was built and why, including how a challenging project, pressure or setbacks were handled. Reviewing every listed technology is safer than relying on a rehearsed summary.
Coding is usually described as moderate. Examples include a stream-based exercise, simple LeetCode-style problems and implementing a stack using queues. One candidate chose between two dynamic-programming problems with 45 minutes to solve one. Another described an online assessment of three DSA problems moving from easy to hard. Difficulty can vary.
Some candidates describe a later managerial, panel or HR stage. One said the manager round stayed fully technical, covering OOP, collections and SQL. Another described a face-to-face conversation mixing technical and HR questions. One microservices conversation ended after about 20 minutes without clear criteria, so asking early how your answers will be assessed can help. Experiences were mixed, with offers, declines and rejections all reported, and details such as the number of rounds differ between candidates.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report different openings. One describes an HR screening, another an online assessment of three DSA problems moving from easy to medium to hard, and another a timed choice between two dynamic-programming problems with 45 minutes to solve one. Check your invite for the format because reports vary.
Most candidates describe a technical round on Java or a related stack, covering Java 8, Spring Boot, OOP, microservices and SQL joins. Coding is typically described as basic to moderate, such as stream exercises, simple LeetCode-style problems or implementing a stack using queues. One candidate faced .NET, React and SQL topics, and another Angular and JavaScript, so the stack may depend on the team.
Several candidates say much of the conversation came from their resume and projects. Interviewers may probe technologies, architecture decisions, or how you handled a challenging project, pressure or setbacks. Prepare specific examples and be ready for follow-ups on any tool you list.
Reports describe a later stage with a manager, panel or HR. One candidate says the manager round remained fully technical, another describes a face-to-face round mixing technical and HR questions, and one mentions a take-home assignment before a final panel. Outcomes vary, with offers, declines and rejections all reported.
