Experience:

An interview experience for an SDE-1 role at Birla Pivot in 2024 was shared on DEV Community.

Round 1 (DSA): This round focused on Data Structures and Algorithms. Specific coding questions mentioned were:

• Given an array `[3,4,9,7,8,9,13,5]` and a sum `12`, find all subarrays by splitting array elements to equal the sum.
• Given an array, find the maximum difference between two numbers `arr[j] - arr[i]` such that `j > i` and `arr[j]` is the maximum.

Beyond DSA, the interviewer also delved into various technical topics, including:

• Spring Boot: Questions on annotations such as `@Controller`, `@RestController`, `@Get`, `@Post`, `@Put`, `@Delete`, `@Repository`, `@Service`, `@Configuration`, `@Component`, `@Bean`, `@SpringApplication` (with `@Autoconfig`), `@CustomAnnotations`, and `@Transactional`.
• OOPs: General Object-Oriented Programming concepts.
• Database: Concepts related to transactions (begin, save points, commit), locking mechanisms, and indexing. Queries for message processing with specific conditions (e.g., `status=notProces`, `retryCount < threshold`, `timestamp < msg.timeStamp + 4days`) were also discussed.
