Technical Bi Analyst Interview Questions
5. Which data modeling software do you prefer to use?
How to Answer
BI analysts mostly use Microsoft Excel or Power BI for their data modeling needs. The required or preferred tools will be most probably listed in the companys job description, so it would be best to refer to those. If you have relevant experience, share your level of expertise with the interviewer. In case you lack exposure to their preferred software or programs, explain how you can incorporate your skills into their systems.
Answer Example
I do most of my data modeling in Excel, as I find it most convenient for data mapping. I have some exposure to Power BI, as well. However, I believe I can benefit from sharpening my skills in that program. Thats why Im currently taking a Power BI online training.
6. What specific technical skills do you have as a BI analyst?
How to Answer
Your BI analyst experience and skillset are closely related to the focus of your career. Depending on whether you are a data BI analyst, an IT BI analyst, or a strategic BI analyst, your answer to this question will be different.
Answer Example
As a data BI analyst, Ive been exposed to data mining and big data software, such as LIONsolver and Oracle. Im highly skilled in Microsoft Excel which I use for data modeling and Power BI where I create rich visuals and client presentations.

Business Intelligence Coding Questions
Coding makes up a large part of the onsite and technical interviews. You’ll have to complete some simple coding exercises that show your proficiency. Typically, you’ll see a lot of SQL questions, as that’s where the lion’s share of the technical work occurs. SQL questions for business intelligence roles tend to as you write queries based on provided data.
Q1. Lets say we have a table representing a company payroll schema.
Due to an ETL error, the employees table did an insert, instead of updating the salaries every year when doing compensation adjustments. The head of HR still needs the current salary of each employee.
Write a query to get the current salary for each employee.
Assume no duplicate combination of first and last names.
employees table:
| column | type || -------------- | --------------- || id | integer || first_name | string || last_name | string || salary | integer || department_id | integer |
Hint: The first step we need to do would be to remove duplicates and retain the current salary for each user.
Given we know there aren’t any duplicate first and last name combinations, we can remove duplicates from the employees table by running a GROUP BY on two fields, the first and last name. This allows us to then get a unique combinational value between the two fields.

products table:

Hiring Decision Process For The Amazon Business Intelligence Engineer Role
Amazon has a concept of bar raisers. A bar raiser is assigned to each interview to ensure each new hire is better than at least 50% of their workforce. Each interviewer except the bar raiser has equal weightage in the hiring decision. The bar raiser holds veto power to either accept or reject a candidate. You will not know the bar raiser for your interview, but you need to show what makes you better than 50% of their workforce.
After the onsite interview, the hiring committee discusses and analyzes how you align with Amazonâs values and leadership principles. Each member may be assigned two to three leadership principles to evaluate you on.
The discussion might raise concerns if your answers diverged from their leadership principles too much, which could lead to rejection via the bar-raiser veto. For example, in an answer, you may have shown focus on competition over customers. That answer shows your traits are orthogonal to customer obsession.
If youâre a good fit for Amazon but arenât a good fit for that team, other hiring managers might interview you further to position you appropriately within the company. If youâre selected, you can also discuss your salary and job expectations after you receive the selection call from your onsite interview. You can expect the call in a day or so.
