Quick Stats

Applied through Wissen Technology's careers portal in September 2026. Being an IT services company, the process was structured and followed a standard pattern. From application to offer took about 3 weeks — typical for IT services companies.

Round 1: Online Assessment

Format: 60-minute aptitude + coding test Duration: 60 minutes What they were testing: Aptitude, Java fundamentals, basic coding Interviewer approach: Automated

The assessment had 3 sections: aptitude (quantitative, verbal, logical), Java-specific MCQs, and 2 coding problems. The coding problems were relatively simple — one involved array manipulation, another was about string processing.

I think the aptitude section was weighted more heavily than I expected. IT services companies seem to value overall problem-solving ability as much as technical skills.

Round 2: Technical Round

Format: 45-minute video call Interviewer: Senior Java Developer Duration: 40 minutes What they were testing: Java fundamentals, Spring Boot, database knowledge Interviewer approach: Traditional — asked questions from a prepared list

The interviewer started with Java basics: difference between HashMap and ConcurrentHashMap, Java 8 features, garbage collection. Then moved to Spring Boot — dependency injection, annotations, and REST controllers.

I was asked to write a simple Spring Boot REST controller for a CRUD operation. I implemented it with proper error handling and validation. The interviewer seemed satisfied with the approach.

His exact words were something like, "Can you explain the difference between @Component and @Service?" Pretty standard question, but he followed up with when to use each annotation in real projects.

Round 3: HR Round

Format: 30-minute video call Interviewer: HR Manager Duration: 25 minutes What they were testing: Communication, willingness to relocate, career goals Interviewer approach: Standard HR questions

This round focused on why I wanted to work at Wissen Technology, my experience working in IT services, and my career goals. I emphasized my adaptability and interest in working with different technologies and clients.

The HR manager asked about my comfort with the hybrid work model — was I willing to come to the office when required? I said I was comfortable with that and appreciated the flexibility.

The Insider Section

Here's something most guides don't mention: Wissen Technology (and IT services companies in general) puts a lot of emphasis on client-facing skills. In my technical round, the interviewer asked how I'd explain a technical concept to a non-technical client. They're not just looking for coders — they want people who can communicate with business stakeholders.

Also, they're big on certifications. The interviewer mentioned that Wissen Technology encourages employees to get certified in Java, Spring, and cloud platforms. Having certifications can help with faster career progression.

Compensation

The offer was ₹14 LPA base with a ₹1 LPA performance bonus. For a Java Developer role in Mumbai in 2026, this is standard for IT services companies. The compensation grows significantly with experience and certifications.

Honest Assessment

Who this role IS right for:

• Engineers early in their career who want structured learning

• Those comfortable with hybrid work and client-facing roles

Who this role ISN'T right for:

• Someone looking for rapid career growth through levels
• Engineers who prefer product development over client projects
• People who want to work on cutting-edge technology exclusively
