You can refer to Snowflake’s Careers page for more in-depth information on the different software engineering profiles and their responsibilities.
Snowflake, being a fast-growing company, considers the recruitment process an integral part of its culture. Focusing on its vision, Snowflake prefers to hire individuals whose ambitions and integrity align with its own. So naturally, you need to be a driven, risk-taker to get hired at Snowflake. Here are the steps you’ll need to take to get noticed by Snowflake and make an excellent first impression:
Before you proceed with your tech interview prep, build a crisp and clean resume. Your resume should highlight your expertise in terms of experiences, skills, and leadership concerning the job role. For instance, if you are a software developer, mention relevant software you have previously worked on. Meanwhile, if you are an engineering manager, highlight your management skills. Likewise, if you are a tech lead, mention the projects you have led previously.
Go to Snowflake’s careers page or eminent job portals like LinkedIn to apply. Browse through the open jobs and apply when you find something that fits. If you set “Open to New Opportunities†as your preference on LinkedIn, recruiters will reach out to you if your profile is suitable for a particular job role.
Snowflake’s interview process consists of the following steps while recruiting employees.
The recruiter will set up a phone screen if your resume gets shortlisted for the desired job role. Since this call is when the recruiters get to know you as an individual for the first time, the first phone screen round is typically pretty casual.
In this round, the recruiter will ask you about your previous relevant experience, why you’re applying at Snowflake, and your views on how you will be adding more value to the company.
For this, it is crucial to know about the company’s history, vision, and exploits beforehand. Browse through Snowflake’s company, ventures, and investor relations to get a clear overview of the company.
After you clear the phone screen round, the recruiter will call you for an onsite or video interview. This onsite or video interview is an in-depth one where the recruiting team will evaluate both your technical and behavioral skills.
Typically, this round will be filled with technical questions, both theoretical and coding-based. Here, you can also expect questions revolving around your leadership and problem-solving skills.
After the interview rounds at Snowflake, successful candidates can have casual conversations with team leads for team alignment. Although meetings with top executives are seldom, your experience can be a justification in pay negotiations.
To help you in your technical interview prep, we have compiled a list of the most important interview questions on Snowflake, along with sample answers for you to go through.
Q: Explain Snowflake Cloud Data Warehouse
A: Snowflake’s data cloud is backed by an advanced data platform working on the software-as-a-service (SaaS) principle. As a result, it facilitates easier, faster, and more flexible data processing, data storage, and analytics solutions compared to traditional products.
These data platforms are not created on pre-existing database technologies or “Big Data†software platforms like Hadoop. Instead, Snowflake works on a new SQL query engine with a cloud-based architecture. Hence, Snowflake can provide all the features of an enterprise analytics database along with other unique features.
Q: How Does Snowflake Differ from AWS?
A: In Snowflake, the storage and calculations are totally independent. So, the storage cost is similar to the data in S3 storage. On the other hand, AWS tries to bypass this issue by introducing a Red Shift spectrum and lets you query data that directly exists in S3. However, it is not as flawless as Snowflake.
Q: Explain Snowflake ETL.
A: Snowflake ETL signifies that the application of the ETL process transfers data to the Snowflake data warehouse. So, you can efficiently extract the required data from the data source. It also facilitates the related transformations to prepare the data analysis and then loads it into Snowflake.
Q: What Are the features of Snowflake?
A: Snowflake comes with the following features:
Q: Explain Snowflake software architecture in brief
Snowflake is a Saas offering built on AWS cloud data warehouse and does not need any software, hardware, or ongoing maintenance and tuning in its operation.
The architecture of Snowflake consists of three major layers which are as follows: database storage, query processing, and cloud services.
Data storage: In the case of Snowflake, the stored data is reorganized into its internal optimized, columnar, and optimized format.
Query processing: Virtual warehouses in Snowflake process queries.
Cloud Services: This layer coordinates and manages all activities across the Snowflake. It provides the best result in terms of Authentication, Metadata Management, Infrastructure Management, Access control, and Query parsing.
Here’s a collection of several commonly asked Snowflake job interview questions:
Before you jump into the syntax and technicalities of the technical interview, make sure you have a clear overview of the database schematics and architecture in your head. You should be able to visualize the database key relations across all the tables.
When the recruiter asks you a question, your solution is not the only thing noted here. How you approach the situation and analyze the problem is what they try to ascertain.
In short, brushing up your technical and conceptual skills and keeping these commonly asked interview questions for Snowflake in mind will remarkably strengthen your tech interview prep.

A Snowflake database is where a company’s published semi-structured and structured data sets are maintained for analysis and management. All aspects of data storage, such as file sizes, compression, metadata, organization, framework, and statistics, are taken care of by Snowflake.
To succeed in a Snowflake interview, it’s fundamental to have a thorough understanding of data warehousing ideas and expertise in dealing with cloud-based data management systems. It is also advisable to keep up with your knowledge of Python, SQL, and data modelling.
The average base salary of a software engineer at Snowflake is around $163,035 per year.
Even while SQL Server has a solid track record for stability, scaling can be an issue, especially with larger data sets. Snowflake, on the contrary, is built for scalability and is capable of handling petabytes of data.
Snowflake can be quite simple to learn, particularly for those who have previous SQL and data warehouse experience.
