    Easy Interview

    Application

    I applied through a recruiter. I interviewed at Interactive Brokers (New York, NY) in August 2020.

    Interview

    Both online and phone screening tech questions are from early 90's HTML 1.0. 90% of questions are old CSS. It looked like the interviewer had a script to read from, and he had no idea what was going on.

    Easy Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Interactive Brokers (Greenwich, CT) in April 2020.

    Interview

    I applied online got a call the same week. Spoke later to 4 gentleman who clearly were not interested in speaking. Very male driven place. The questions were basic but sometimes they would ask very personal information which clearly has nothing to do with the job. Red Flag there. Then they ask you to take this test which has nothing to do with the job. Not sure why the interview process is so outdated.

    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Interactive Brokers in April 2020.

    Interview

    The in-house recruiter reached out to me via Vettery, and I ended up having a great conversation over the phone. He went over job details and told me about Interactive Brokers team and the company, we also talked about other industry related topics.

    The next step was an online Codility test, and then I moved on to the next round. Since this was during the Covid-19 pandemic, the next round of the interview was coordinated through GoToMeeting. The interview was with two of the hiring managers. The first asked me a lot of in depth Java questions and few other technical questions. The 2nd manager was interested in my general industry knowledge and interests. He ask many technical questions, but not all related to software development. He was evaluating how much I paid attention to the developing technologies, how they are utilised in software development or applied in everyday life.

    Overall I had a very positive experience and learned a few new things along the way. Just from the conversations alone I can see that there are many smart and talented engineers at IB.

    Interview Questions

    • Online Codility test with one Java and SQL task.   1 Answer

    I applied online. The process took a week. I interviewed at Interactive Brokers in March 2020.

    Interview

    As described by many others, the firm has a not very good interview process and seems like they don't value their candidates time. It seems to me everyone who applies gets a test and if you pass the test, the recruiter actually takes a look at your resume, rather than the other way around.

    Interview Questions

    • I had a bunch of multiple choice questions which were of average difficulty. Preparation materials: https://www.geeksforgeeks.org/c-plus-plus/.   1 Answer

    Interview

    Math Online Test (think Algebra) + Online Coding Test (easy to medium level difficulty) + Online Personality Test (No idea why this is being used). Followed by a phone screen and then a virtual onsite

    Interview Questions

    • Obscure questions about Java and specific libraries. Interviewers were condescending and arrogant. This company is not language agnostic in their interview approach and ask extremely obscure java questions. They do not consider problem-solving and just want pure in depth textbook answers for java trivia questions (even if you don't code in Java and Java isn't on your resume). Very outdated and out of touch hiring process compared to modern companies. This explains their low glassdoor rating, the company culture is a mess, dodged a bullet.   Answer Question
