Banking Domain Interview Questions and Answers

1. Explain the concept of a ledger in banking systems and its importance.

A ledger in banking systems is a comprehensive record of all financial transactions within an organization. It serves as the primary source of financial data, recording every transaction, including debits and credits, and categorizing them into various accounts such as assets, liabilities, equity, revenue, and expenses.

The importance of a ledger in banking systems includes:

  • Accuracy and Transparency: Ledgers ensure that all financial transactions are accurately recorded and can be easily traced, aiding in auditing and regulatory compliance.
  • Financial Reporting: Ledgers provide the data needed to generate financial statements, essential for stakeholders to assess the financial health of the organization.
  • Decision Making: Accurate ledger records enable informed management decisions based on the organization’s financial position.
  • Fraud Detection: Regularly updated ledgers can help detect and prevent fraudulent activities by highlighting discrepancies.
  • Regulatory Compliance: Maintaining a detailed ledger helps ensure compliance with financial regulations and standards.

2. Write a SQL query to find the top 5 customers with the highest account balance.

To find the top 5 customers with the highest account balance, use the SQL ORDER BY clause to sort results in descending order based on the account balance, and the LIMIT clause to restrict the number of results to 5.

Example:

SELECT customer_id, customer_name, account_balance
FROM customers
ORDER BY account_balance DESC
LIMIT 5;

3. Explain the role of KYC (Know Your Customer) in banking.

KYC (Know Your Customer) is a regulatory requirement aimed at verifying the identity of clients to prevent financial institutions from being used for money laundering. It involves:

  • Customer Identification: Collecting and verifying documents to confirm the identity and address of the customer.
  • Customer Due Diligence (CDD): Assessing the risk profile of the customer based on their financial activities.

  • Risk and Complexity: Corporate banking deals with more complex and higher-risk products.

5. How would you ensure data consistency in a distributed banking system?

Ensuring data consistency in a distributed banking system is essential due to the nature of financial transactions. Strategies include:

  • ACID Transactions: Implementing ACID properties ensures reliable transaction processing.
  • Eventual Consistency: Acceptable in systems prioritizing high availability over immediate consistency.
  • Consensus Algorithms: Algorithms like Paxos or Raft achieve consensus among distributed nodes.
  • Data Replication: Replicating data across nodes improves fault tolerance and availability.
  • Conflict Resolution: Strategies like version vectors manage concurrent updates.

6. Describe the process of loan origination and the key steps involved.

Loan origination involves several steps:

  • Pre-Qualification: Initial assessment of the borrower’s eligibility.
  • Loan Application: Completion of a detailed application form.
  • Application Processing: Verification of the information provided.

}

# Create DataFrame
df = pd.DataFrame(data)

# Define thresholds
large_transaction_threshold = 10000
high_risk_countries = ['CA']

# Identify large transactions
df['large_transaction'] = df['amount'] > large_transaction_threshold

# Identify transactions from high-risk countries
df['high_risk_country'] = df['country'].isin(high_risk_countries)

# Identify frequent transactions just below the threshold
df['suspicious_amount'] = df['amount'] > (large_transaction_threshold * 0.9)

# Filter suspicious transactions
suspicious_transactions = df[(df['large_transaction']) | 
                             (df['high_risk_country']) |
