The Danger Zone: Top Reasons Candidates Fail

Based on our database of Erste Group Bank interview outcomes, avoid these common traps:

Coding Screen

2
Type · algorithmic
Given a stream of stock prices for a particular security, design an algorithm to detect if the price has crossed a certain threshold (e.g., a moving average) within a given time window. Optimize for memory and time efficiency.
3
Type · algorithmic
Implement a function that takes a list of financial transactions (each with an amount and timestamp) and returns the N most frequent transaction amounts within the last hour. Use appropriate data structures.

System Design

4
Type · system-design
Design a system to process and validate real-time financial market data feeds from multiple exchanges. Consider aspects like data ingestion, validation, normalization, and low-latency delivery to downstream services.
5
Type · system-design
Design a rate limiter for API requests to our core banking services. The rate limiter needs to be highly available, scalable, and support different limits per API endpoint and per customer tier.

6
Type · coding
Write a function to calculate the Value at Risk (VaR) for a portfolio of assets. Assume you have historical price data for each asset. Discuss the different methods (e.g., historical simulation, parametric) and their trade-offs.
7
Type · debugging
Here is a piece of code intended to calculate the daily closing price for a set of stocks, but it contains several bugs. Debug and fix the code, explaining your thought process.
