Real, anonymous reports from people who interviewed for Software Engineer at airtel, newest first and distilled into what to expect across the loop.
After a recruiter call, I ended up doing an online assessment and then a technical round focused heavily on Java and databases. The Java part leaned on collections concepts like list and related basics, and the DSA portion involved working through a linked-list problem where I had to apply a reverse approach. The database questions felt practical: I got a scenario around a cab booking system and was asked to optimize a query by using normalization and adding indexes on relevant columns.
My interview journey started with the technical screening being scheduled after an HR conversation, and it quickly turned into a Spring Boot and microservices-focused evaluation. I was checked on a mix of Java and backend frameworks, including Spring Boot architecture and how auto-configuration fits together. I also got into details like the difference between @Component and @Bean, and we walked through @Transactional behavior using isolation levels with real use-case style scenarios.
The interview process typically begins with a technical screening that includes coding and data structure questions, often focusing on Java, DSA, and sometimes SQL. Candidates should be prepared for a mix of problem-solving and practical application questions related to their resume.
Later rounds often involve system design discussions where candidates are asked to design applications or explain architectural decisions, emphasizing scalability and trade-offs. Familiarity with concepts like microservices, LLD, and HLD is beneficial.
The final stages usually include HR discussions that focus on behavioral questions and situational responses, often framed around candidates' past experiences and how they relate to the role. Candidates should be ready to discuss their projects and career aspirations.
Candidates generally report a moderate to high level of difficulty across the interview stages, with a structured flow that gradually increases in complexity. It’s important to maintain clear communication and articulate thought processes during problem-solving.
Throughout the interview process, there is a strong emphasis on foundational knowledge in programming concepts, data structures, and algorithms. Candidates should be prepared to explain their reasoning and approach rather than just providing correct answers.
The overall atmosphere of the interviews is described as professional yet supportive, with interviewers willing to engage and assist candidates during technical discussions. This can help alleviate some pressure and foster a more collaborative environment.
