People always think that Splunk is a "logging company", but in fact it has long been transformed into a powerful data platform, and the requirements for engineers are becoming more and more "hardcore"! Many students who come to Programhelp say:Splunk The interviews are more skewed towards system engineering than expected, especially the coding questions are very practical, and the system design questions are very much on the mindset of the interviewer. This article is based on real coaching cases, we disassemble the whole interview process + high frequency test points, hope to help you less detour, sprinting to the big factory offer!
Splunk Software Engineer job: complete interview process breakdown
Stage 1: Resume Submission & Initial Screening
You can apply via the official website or inbound from employees, and a technical background in log analytics, big data processing, or distributed systems experience is a plus.
Stage 2: Online Assessment (OA)
Usually complete moderately hard algorithmic problems at HackerRank, with scenarios that fit into the real world of engineering.
Stage 3: Technical telephone interviews (1-2 rounds)
Live coding Examines the ability to write code, optimize and debug, mostly seen in tool implementations such as log processors, caching modules, etc.
Phase IV: Onsite / Virtual Onsite (4-5 rounds)
- Coding interviews (2 rounds): Practical questions on log data parsing, event stream processing, and more.
- System Design (1 round): Design of log indexing system, metrics monitoring framework.
- Behavioral interview (1 round): Teamwork, commissioning process and technical decision making thinking.
Splunk Sample Questions
Round 1: The longest continuous path of the grid
Given a h × w rectangular grid containing all integers from 1 to n, find the maximum length of a path of successive increases and decreases (difference 1) of numbers.
Problem Solving Ideas:
- Store the grid in a two-dimensional array and use a dictionary to record each number position.
- Do DFS with memo for each lattice to explore the longest path.
- Move in all four directions, recursive if neighboring digits differ by 1.
- Takes the maximum value globally.
Round 2: URL de-duplication and merging (HR interview)
Given 10 billion unsorted URLs, how to de-duplicate and merge them when out of memory?
Programs:
- Data slicing:Split buckets by hash to reduce the amount of data in a single bucket.
- Write to disk:Write the file to the slice.
- External sorting & de-duplication:Each bucket is de-duplicated using external subsumption sorting with sequential scanning.
- Consolidated results:Each slice is de-weighted and then directly merged.
Can be combined with parallel processing, Bloom filters and incremental de-duplication optimization.
Round 3: System Design - Web Crawler
Design a crawler that recursively grabs web pages and stores the content.
Module Design:
- Input Interface:Receives an initial list of URLs.
- Grab:Asynchronous or multi-threaded request to fetch HTML.
- Parsing:Extract hyperlinks.
- De-duplication queue:Collection/Bloom filter management URLs.
- Storage:Save to relational/NoSQL/file system.
- Speed limits and error handling:Retries, logs, frequency limits.
- Expansion:Distributed crawling, dynamic pages, task monitoring.
