  1. Imagine you're designing a new feature for the Bank of America mobile app that allows users to instantly transfer money between their BoA accounts and accounts at other banks using a secure token-based system. Describe the high-level architecture, focusing on how you'd handle potential race conditions during transfers and ensure data consistency across different systems. What external APIs would you consider integrating with?

    Software EngineerSystem DesignTests: Evaluates system design thinking, understanding of distributed systems, and ability to anticipate and mitigate technical challenges in a financial context.

  2. A critical bug has been reported in the BoA online banking platform where users are intermittently seeing incorrect account balances after completing a transaction. Users are frustrated and reporting it on social media. Walk me through your debugging process, from initial report to identifying the root cause and proposing a solution. What tools and strategies would you employ?

    Software EngineerDebuggingTests: Assesses problem-solving skills, systematic debugging approach, and ability to work under pressure in a production environment.

  3. We're seeing a significant increase in fraudulent transactions originating from suspicious IP addresses targeting our credit card services. Design a real-time fraud detection system that can identify and flag these transactions before they are processed. Consider the trade-offs between false positives and false negatives, and discuss the technologies you'd use.

    Software EngineerSystem DesignTests: Tests understanding of security, real-time data processing, and the application of algorithmic solutions to financial fraud.

  4. Write a SQL query to find the top 5 most active BoA checking account holders in the last quarter, defined by the number of transactions (deposits and withdrawals) greater than $100. Assume you have tables `accounts` (account_id, customer_id, account_type) and `transactions` (transaction_id, account_id, transaction_type, amount, transaction_date).

    Data ScientistSQLTests: Evaluates proficiency in SQL for data extraction and analysis relevant to banking operations.

  5. Bank of America is considering launching a new feature in its mobile app to offer personalized investment advice powered by AI. How would you design an A/B test to measure the effectiveness of this new feature? What key metrics would you track, and how would you determine statistical significance?

    Data ScientistExperimentationTests: Assesses understanding of experimental design, A/B testing methodology, and metric selection for product evaluation.

  6. You are a Product Manager for the Bank of America mobile app. A competitor has just launched a new feature that allows users to round up their everyday purchases to the nearest dollar and automatically invest the difference. How would you assess this competitive threat and decide whether Bank of America should build a similar feature? What would be your product strategy?
