Splunk Software Engineer Interview Guide
The Splunk Software Engineer interview is usually broken up into three stages: the first screen, the technical screen, and the on-site round.
LAUNCH your dream career!
Talk to a coach from your target company for:
The initial screen is a one-hour telephonic interview with the recruiter. Typically, the initial screen features questions related to your CV and work experience, if any. The first screen is meant to see if the candidate is interested in the job and if they have the right experience and skills for the job and the company. People who are just out of college should be very careful with their CV and any projects or internships they may have had while they were there.
Most asked interview questions in the Initial Screen.
- What made you decide to become a software engineer?
- Why Splunk?
- What do you know about Splunk?
The technical screen is a one-hour interview with the hiring manager and a Splunk software engineer. This round is aimed at assessing your technical skills in the following areas:
- Coding
- Systems Design
- Algorithms and Data Structures
Coding
There will be questions on the technical screen that test the candidate’s general programming skills in the “coding aptitude” section. The focus will primarily be on object-oriented programming. Students need to be proficient in at least one of the programming languages among C++, Java, and Python. Also, questions to test your clarity of the OOP concept may be asked. Typically, the interviewer asks 2-3 coding questions that need to be attempted through a shared online code editor.
Most commonly asked Coding questions in the Technical screen:
- Here’s some Python code to see if a substring is part of a given string:
- Write Python code that will accept strings with only vowels.
- Given a matrix of size r*c. Traverse the matrix in spiral form.
- Here’s the code to add an item to the middle of a linked list:
- You can turn a sorted list into a binary search tree by writing a function.
- Here’s some code to see if an array is part of another array:
- Use all four pillars of the oops concept to make a class of university management system.
System Design
Systems design includes things like system architecture, product design, modules, interfaces, and data that a system needs to meet certain needs. The interviewer may ask questions on front-end design, back-end design, scalability, and more in this section.
Most asked Splunk Software Engineer interview questions on System Design
- Can you design a database system for a Supermarket?
- Design a secure password system for wearable devices
- How would you design and build the different modules of a recommendation system that is based on core attributes and features?

- Tell me how you would handle versioning of Web Services APIs.
- Design Splunk Design Server driven system.
Algorithms and Data Structures
Algorithms and data structures is a staple of almost all Software Engineering interviews, and Splunk is no different. Question areas to focus here would be Linked Lists, Queues, Stacks, Binary Search Trees, and Arrays.
Most asked Splunk Software Engineer interview questions on algorithms and data structures:
- Given a list of n integers and the number Z, you need to write an algorithm that finds all the pairs of integers (a,b) whose sum is Z.
- Design LRU using basic data structures.
- Come up with a way to do preorder traversal in a binary search tree.
- How would you handle dependencies between assets? What kinds of data structures can help you handle different kinds of dependencies?
- Give the code to find the word that appears most often in a paragraph.
The onsite round is an extended version of the phone screen. It is conducted on Splunks campus, and consists of 4 rounds, two technical, and two behavioural. The technical rounds last for an hour each, and the behavioral round lasts for an hour and a half. After the first interview, you’ll have a 15-minute lunch meeting with a current software engineer where you can ask any questions you have about the role, responsibilities, etc.
Technical Round 1
The technical rounds are conducted by a senior software developer at Splunk.
The first technical round would mostly feature coding questions. It will feature at least two coding problems. Candidates should be prepared to code in C/Java, or Python.
Most asked coding questions in the Onsite Round:
- Given n numbers (P1,P2,P3,. Pn). Split them into m separate parts so that the sum of the highest and lowest numbers is
- Write a program that will add the numbers in a string. For example, if you give the string Gl223a45ssd908oo6r, the program should return 223 x 45 x 908 x 6 = 1182.
- Come up with a way to find the middle item in a list that is only linked to itself.
- Write code that will look for an item in a Binary Search Tree.
- Writing a function to find all integer pairs whose sum is equal to a certain number is what you need to do.
- Given a character array, calculate the minimum no. of jumps from 1st alphabet to reach the last alphabet. CRITERION: From a given character, you can either: 1. Jump to the adjacent character 2. Jump to the same character positioned in a different place.
Technical Round 2
The second technical round will feature system design questions. It will feature at least 2-3 system design questions. Interviewers may ask back-end design, frontend design, as well as scalability questions.
Most commonly asked System Design question in the onsite round
- Create a backend application using an in-memory database.
- Draw low level design of online bus booking system.
- Design a Billing System for a cloud-based Platform.
- Create a system that tells a user about all the restaurants within 2 km of where they are.
- Plan for a poker game with several tables and six chairs at each table. And the system has to give the people in line the seats that are available. And each participant will be allocated 100 poker chips.
Behavioural Rounds
The two behavioural rounds are aimed at assessing behavioural aspects of your personality. You may be asked situational questions as to how you tackled a particular situation. The people interviewing you may also want to know why you want to be a software engineer or why you chose Splunk. There may also be a few scenario-based questions to test your leadership skills.
The most fundamental thing to keep in mind in behavioural interviews is tobe honest in your replies. Always expect that you and the interviewers will go back and forth over a question or answer, so be ready for that.
Most commonly asked questions in the Behavioral section
- Why have you chosen to apply to Splunk?
- What made you decide to become a software engineer?
- Where do you see yourself in the next 10 years?
- Tell me something about your approach to goal-setting.
- How do you handle pressure at work?
- What’s the best thing about working with other people?
- Have you ever been unmotivated at work? If so, what did you do to get back on track?
- Stick to the “Think out loud” method to show the interviewers how you’re going to answer. Make sure not to rush to answer any question.
- Do not hesitate to ask clarifying questions.
- Get to know Splunk’s values, work culture, and other things before the behavioral interview. Also, prepare some examples to use in the scenario-based questions about your past jobs, including what you did well, what problems you had, and how you solved them.
With the above pointers, we are sure you would crack the Splunk Software Engineer interview. Hope you found the guide useful.
