I applied online. The process took 2 weeks. I interviewed at ION Trading (New Delhi) in May 2010
Interview
I applied thru Nauri.com. Received a call from HR. HR explained whole process in details. First it was technical interview on phone. Interviewer was a senior developer. He asked good questions on language (Java) and focused on OOPS, design skills, design patterns, threading etc. Next was written test - a good one but there are few confusing questions. Next was one on eone interview with Noida developers. Pretty lengthy - they covered almost all aspects - OOPS, designing, threading, collections, database, OS, etc. Next was another technical round through VC. I did not have prior expereince with VC. Therefore, it was a tough expereince. Voice was not very clear. I had to struggle. But guys on other end were supportively and I think they understood my position. Final round was interview with Delhi Director. It was more a personality check with focus to check your stability and sutability for company. I was provided with all important details about ION in this interview. Overall it was very lengthy process. I am happy as I cleared all the rounds. Feel proud of myself!
Good process. In-depth understanding of concepts required. Detailed answers expected. Great questions right from management, technical, and hr. Overall confidence throughout the interview process is very important. They hired a good number of people from campus.
The first stage was a test comprising of aptitude questions and 2 coding questions of average difficulty. After this interview happened virtually on Microsoft Teams. There were two people who took the first round of interview. Rest of it happens on ION day.
