I applied through a staffing agency. The process took 1 day. I interviewed at Wissen Infotech (Bengaluru)
Interview
It was hiring for one of their client, first round was online test, followed by a written programming test and then one round of technical interview and a round of white board marker interview.
It took around half day process was good, questions were not new but interesting.
After the interview asked me to leave for the day, and 2 days after I got a call from them for client round they took my PAN and said they will share the schedule, after that I never heard anything from them.
Interview questions [1]
Question 1
Some string programs , mutithreading related questions, hashmap implementation, linked lists, design pattern like builder, factory etc
I applied through a recruiter. I interviewed at Wissen Infotech (Andheri East) in Dec 2025

Interview Experience – Wissen Technology (Senior Java / Spring Boot)
The interview process was lengthy and inconsistent. Initially, the process involved a HackerRank round followed by multiple technical interviews. I was rejected at the 3rd technical round, even though I was informed there would be up to 5 technical rounds, which felt excessive for a senior-level role.
Later, I was again invited to an offline mass hiring test with around 50 candidates. The task was to write a complete Spring Boot application to read a CSV file, parse it into POJOs, and persist data into an H2 database — without internet access. This felt more like a memory-based elimination test rather than a real-world evaluation of engineering skills.
The setup did not differentiate between experience levels, and senior candidates were assessed using the same process as juniors. The overall experience lacked clarity, respect for candidate time, and alignment with real-world development practices where documentation and tools are normally used.
Suggestion: Streamline the interview process, reduce the number of technical rounds, and design evaluations that focus more on problem-solving and system understanding rather than memorization.

asked deep questions on oops and java collections and hashmap ,threads,inheritance solve Highest Average Score Among Students problem. again in round 2 was about springboot and microservices asked about dependency injection
Total 5 technical rounds, 1 st round being very basic and easy. Then comes technical rounds check basic knowledge and problem solving.
Round 1 tech, round 2 tech , client round 1 , client round 2, hr round
