Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις Banking Circle

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · System Design

Design a rate limiter for API requests to protect backend services from overload. The rate limiter should be distributed, meaning it can operate across multiple instances of your API gateway or service. Consider different strategies (e.g., token bucket, leaky bucket) and discuss trade-offs in terms of accuracy, performance, and memory usage.

Τύπος · Algorithmic

You are given a list of financial instruments, each with a unique ID, a current price, and a list of historical prices. Write a function that, for each instrument, calculates the percentage change from its 7-day moving average. Return a dictionary mapping instrument IDs to their calculated percentage changes. Handle cases where an instrument has fewer than 7 historical prices.

Τύπος · Debugging

Here is a snippet of code intended to calculate the total value of a user's portfolio across different assets. It appears to be returning an incorrect total. Please debug this code, identify the root cause of the error, and provide a corrected version. ```python portfolio = { 'stocks': [{'symbol': 'AAPL', 'quantity': 10, 'price': 150.00}, {'symbol': 'GOOG', 'quantity': 5, 'price': 2700.00}], 'crypto': [{'symbol': 'BTC', 'quantity': 0.5, 'price': 40000.00}, {'symbol': 'ETH', 'quantity': 2, 'price': 3000.00}] } def calculate_total_portfolio_value(portfolio_data): total_value = 0 for asset_type, assets in portfolio_data.items(): for asset in assets: total_value += asset['quantity'] * asset['price'] return total_value print(f'Total portfolio value: {calculate_total_portfolio_value(portfolio)}') ```

  1. 2

    Τύπος · Algorithmic

    Imagine you are building a real-time transaction monitoring system. Given a stream of transaction events (each with sender ID, receiver ID, amount, currency, and timestamp), design an algorithm to detect and flag suspicious patterns, such as unusually large transactions or rapid sequences of small transactions between the same parties within a short time window. You need to return a list of transaction IDs that are flagged.
  2. 3

    Τύπος · Algorithmic

    You are given a list of financial instruments, each with a unique ID, a current price, and a list of historical prices. Write a function that, for each instrument, calculates the percentage change from its 7-day moving average. Return a dictionary mapping instrument IDs to their calculated percentage changes. Handle cases where an instrument has fewer than 7 historical prices.

  1. 4

    Τύπος · System Design

    Design a system for real-time fraud detection in payment processing. The system needs to ingest millions of transactions per day, analyze them against various fraud rules and machine learning models, and provide a fraud score or decision within milliseconds. Consider scalability, fault tolerance, and the ability to update fraud rules dynamically.
  2. 5

    Τύπος · System Design

    Banking Circle facilitates cross-border payments. Design a system to reconcile incoming and outgoing payments across multiple currencies and correspondent banks. The system must handle high volumes, ensure accuracy, and provide clear reporting on settlement status and discrepancies. Consider potential failure points in the payment chain.

  1. 6

    Τύπος · Coding

    Implement a function `process_batch_payments(payment_requests)` that takes a list of payment requests. Each request contains sender, recipient, amount, and currency. The function should group payments by currency, process them in parallel for each currency, and return a summary of successful and failed payments per currency. Ensure that within each currency group, payments are processed sequentially to avoid race conditions on shared ledger balances (assume a `process_single_payment(payment)` function exists that handles ledger updates and returns success/failure).
  2. 7

    Τύπος · Debugging

    Here is a snippet of code intended to calculate the total value of a user's portfolio across different assets. It appears to be returning an incorrect total. Please debug this code, identify the root cause of the error, and provide a corrected version. ```python portfolio = { 'stocks': [{'symbol': 'AAPL', 'quantity': 10, 'price': 150.00}, {'symbol': 'GOOG', 'quantity': 5, 'price': 2700.00}], 'crypto': [{'symbol': 'BTC', 'quantity': 0.5, 'price': 40000.00}, {'symbol': 'ETH', 'quantity': 2, 'price': 3000.00}] } def calculate_total_portfolio_value(portfolio_data): total_value = 0 for asset_type, assets in portfolio_data.items(): for asset in assets: total_value += asset['quantity'] * asset['price'] return total_value print(f'Total portfolio value: {calculate_total_portfolio_value(portfolio)}') ```

    Τύπος · Collaboration

    Describe a situation where you had a technical disagreement with a colleague or team lead regarding a design decision or implementation approach. How did you handle the disagreement, what was the process for reaching a consensus, and what was the final decision?
