How 6 Targeted Questions Reveal the True Experience of 2‑Year Java Candidates

During the peak interview season, the team received eight Java resumes that had already passed HR screening. The author observed a persistent pattern over the past decade: many candidates with 2‑3 years of experience exaggerate their work history, often listing projects they never actually built.

Resume analysis highlighted several issues: two candidates appeared to pad training‑center projects; two resumes contained careless errors and incorrect technology names; two used outdated stacks such as Struts2; and the remaining two described average projects that would likely need mentorship after hiring. Common problems included poor formatting, vague responsibility statements like "implemented XXX using YYY," and a lack of polished presentation, which the author notes often correlates with lower code quality.

Despite suspecting padding, the team chose a candidate whose technology stack aligned best with the company's needs, hoping the applicant might be among the few genuine performers.

Interview Question 1: "Describe your team composition and the number of microservices." The candidate listed product manager, project manager, front‑end, back‑end, UI, and architect, and claimed the project had 30 microservices. The author found this implausible given the candidate’s experience level.

Interview Question 2: "If an interface calls services A, B, and C and C fails, what do you do?" The candidate could not answer, suggesting no real experience handling multi‑service failure scenarios.

Interview Question 3: "Explain your understanding of clustering and distributed systems." The response was vague and generic, further raising doubts about hands‑on experience.

Interview Question 4: "Why choose RabbitMQ over other MQs, and how do you prevent duplicate consumption?" The candidate failed to mention using a database unique index for idempotency, instead suggesting Redis checks or row locks, which did not address the core issue.

Interview Question 5: "How would you ensure safety, concurrency, and idempotency for order and payment callbacks?" The candidate did not discuss distributed locks or proper transaction handling, indicating limited depth in payment‑related development.

Interview Question 6: "In a Nacos‑registered microservice environment, how does service A call B and C?" After stumbling, the candidate searched online and eventually mentioned OpenFeign, revealing a lack of prepared knowledge.

The author concludes that the candidate’s resume likely contained inflated claims, used a training‑center framework (elegent), and did not follow the STAR method for describing responsibilities. The article advises candidates to craft well‑structured, honest resumes and interviewers to develop keen screening skills to spot inconsistencies.
