How to Prepare for a Business Analyst Interview

Whether you are a new graduate or already having working experience, we are ready with the best solutions for your interview. From having memorized all basic business analyst interview questions to figuring out how to interview an economist, for example, you can be sure that this article will cover them all in one go.

In order to be well-prepared for an interview, it is mandatory to first be well-acquainted with the role of the business analyst. Business analysts close the gulf between IT and company by using data analytics to appraise processes, determine necessities, and make suggestions based on data. They take on the main part of advising institutions to take informed decisions and improve their own operations.

The main duties of a business analyst are:

Recognizing and evaluating the business problems
Collecting and recording the requirements
Producing a detailed business analysis
Communicating the results to the stakeholders
Implementing and testing the solutions

Business Analyst Problem Statement :-

Uber faces an issue where some drivers ask customers to cancel rides upon reaching the pick-up point and then unofficially complete the rides, impacting Uber’s revenue. As a data analyst, identify these drivers using available data points to address this problem effectively.

Solution:-

1. Fetch the List of Drivers with High Cancellation Rates:
- Objective: Identify drivers whose rides are frequently canceled by customers after reaching the pickup point.
- Approach: Query the ride data to find drivers with a high number of cancellations at the pickup point. This can be done by analyzing the timestamps and cancellation reasons.

2. Fetch Drop Points of the Canceled Rides:
- Objective: Gather data on the drop-off locations associated with rides that were canceled at the pickup point.
- Approach: Extract the drop-off locations from the ride data for the rides that were canceled.

3. Check GPS Location of Drivers Post-Cancellation:
- Objective: Determine the exact location of drivers immediately after the ride cancellation.
- Approach: Use GPS data to track the driver's location when they mark themselves as available again after the cancellation.

4. Proximity Analysis:
- Objective: Check whether the driver's post-cancellation location is within a 0-2 km radius of the drop-off point of the canceled ride.
- Approach: Calculate the distance between the driver's location (when they become available again) and the drop-off location of the canceled ride. Use geospatial calculations to determine if this distance is within the specified radius.

5. Identify Suspicious Drivers:
- Objective: Identify drivers who frequently appear within the 0-2 km radius of the drop-off points of canceled rides and immediately mark themselves as available.
- Approach: Compile a list of such drivers by analyzing the proximity data and their availability status. This list will include drivers who exhibit a pattern of cancellations followed by availability near the drop-off points, indicating potential misuse of the system.

By following these steps, you can systematically identify drivers who might be misusing the system.

1. What are the different subsets of SQL?

Data Definition Language (DDL) – It allows you to perform various operations on the database such as CREATE, ALTER, and DELETE objects.
Data Manipulation Language(DML) – It allows you to access and manipulate data. It helps you to insert, update, delete and retrieve data from the database.
Data Control Language(DCL) – It allows you to control access to the database. Example – Grant, Revoke access permissions.

2. List the different types of relationships in SQL.

There are different types of relations in the database:
One-to-One – This is a connection between two tables in which each record in one table corresponds to the maximum of one record in the other.
One-to-Many and Many-to-One – This is the most frequent connection, in which a record in one table is linked to several records in another.
Many-to-Many – This is used when defining a relationship that requires several instances on each sides.
Self-Referencing Relationships – When a table has to declare a connection with itself, this is the method to employ.

3. How to create empty tables with the same structure as another table?

To create empty tables:
Using the INTO operator to fetch the records of one table into a new table while setting a WHERE clause to false for all entries, it is possible to create empty tables with the same structure. As a result, SQL creates a new table with a duplicate structure to accept the fetched entries, but nothing is stored into the new table since the WHERE clause is active.

4. What is Normalization and what are the advantages of it?

Normalization in SQL is the process of organizing data to avoid duplication and redundancy. Some of the advantages are:
Better Database organization
More Tables with smaller rows
Efficient data access
Greater Flexibility for Queries
Quickly find the information
Easier to implement Security

ENJOY LEARNING 👍👍

Many people get data analysts and business analysts confused.

They are very different roles.

Here's the main differences:

1. Focus and Purpose

BA's understand and improve business processes, strategy, and operations.

DA's focus is on analysing and extracting insight from data.

2. Skillset

BAs need to understand business processes and facilitate effective solutions.

They act as orchestrators between various technical and non-technical teams.

DAs need to be able to analyse and extract insights and communicate data-driven recommendations.

3. Data Focus

BAs aim to understand the link between data and business thoroughly. In complex environments, this is key, as success often depends on the efficiency of technical teams.

DAs, on the other hand, primarily focus on doing things with data.

4. Output

BAs deliver business requirement documentation, make strategic recommendations, and sometimes act as project managers to help get initiatives over the line.

Analysts deliver reports, dashboards, models, etc. Both create and deliver presentations.

5. Tools

As mentioned, BAs dive into the theory that underpins data and business logic, and therefore their tools reflect this. Jira, Visio, confluence, etc. are all common.

Analysts use more technical tools like SQL, Python/R, PowerBI, and Tableau.

Both use spreadsheets.
