First-hand accounts from people who interviewed at ION Group.
Rotational Analyst
The interview process kicked off with a skills assessment, followed by a first-round behavioral interview with two interviewers. The final stage was an in-person superday, which went on for almost six hours. The superday included three behavioral interviews, a group case study, and an individual case study, and honestly, there wasn't enough time to finish the case properly. The whole thing was a bit of a drag, taking about four months from start to offer. The company vibe felt pretty depressing, and some of the first-year analysts seemed unprofessional and condescending during the superday. For the pay and location, a 5-6 hour superday with case studies felt excessive. There was also no clear info on rotations or training, making the program seem unstructured.
- Can you share an instance where you utilized data?
Software Development Engineer
First was OA with 2 DSA questions (medium) and some normal output/reasoning questions. Second was a 30 min technical round on DSA, OOPS, and resume, asking 'why' for everything and basics, especially hashmaps and heaps. They also asked puzzles to others, GFG style. Third was a case study round with a business problem and data questions, testing thinking, logic, and quick maths, not technical. Fourth was another technical round, mixing resume/OOPS theory and case study elements, no coding, just theory on resume stuff. Fifth was a 2-hour behavioural round with India Head, a GD with 6 candidates. Sixth was a 20 min culture fit with Italy Heads, basic-medium technical and some behavioural questions.
- The technical round focused on DSA, OOPS, and my resume, lasting 30 minutes, where they asked 'why' for everything and basics, especially regarding hashmaps and heaps. They also posed puzzles to other candidates, and they really like GFG questions, so be prepared.
- There were puzzles asked to other candidates, these guys love GFG (GeeksforGeeks) questions, keep them handy.
Technical Analyst
First, there was an online assessment that lasted 90 minutes, covering Aptitude and CS fundamentals. Then came the Technical Interview, where they asked about Puzzles (like GfG), Guesstimates, and went into detail about Projects and Past Internships. They also threw in some Tricky Situation Based HR questions and asked for Basic Coding Problems in your primary language. Finally, there were 2 SQL easy-moderate problems.
- Could you solve some coding problems in Python, specifically involving dictionaries?
- Can you explain SQL joins?
- How about database indexing, could you explain that?
Data Scientist
The interview process was conducted on campus. It started with an online round which included multiple-choice questions on core concepts, SQL, and some SQL coding problems. This was followed by a technical interview where I was asked about my introduction, presented with a puzzle, questioned about my resume, tested on basic DBMS concepts, and asked about Pandas and SQL queries.
- Could you provide some pandas queries on a given table?
- Can you write a SQL query to find the second highest salary?
