Equifax Software Engineer interviews typically start with an online assessment, move through one to three technical rounds on DSA, Java, and SQL, and close with an HR or behavioral round.

Equifax's Software Engineer interviews usually open with an online assessment and then move into live technical rounds before a closing HR conversation. The assessment typically mixes aptitude or verbal questions, multiple-choice questions on core CS subjects like DBMS and OS, and one or two coding problems at an easy-to-medium level. One candidate took an SHL test as the first gate.
Live technical rounds lean on data structures and algorithms fundamentals. One candidate was asked to count occurrences of numbers from 1 to 100 without maps or filters, then without even a count variable. Others worked through binary search tree implementation, Fibonacci recursion, a stack built on a linked list, the first non-repeating character in a string, and a stock buy-and-sell problem refactored for better complexity. SQL shows up repeatedly, with questions like finding the second-highest salary or explaining inner joins. Java core concepts such as multithreading, exception handling, and the collections framework also recur. In one panel interview, a candidate also fielded networking basics (OSI layers, TCP versus UDP), Git workflow, and authorization and authentication questions, some outside what was on their resume.
Expect a resume and project walkthrough covering what you built and the technologies you chose. A closing HR round covers strengths, weaknesses, relocation, and occasionally workplace scenarios. Most candidates in these reports did not receive offers. The technical bar is generally described as moderate, so explaining fundamentals clearly matters more than solving unusually hard problems.

I started with an online assessment that had three distinct sections: aptitude questions, core CS subjects, and two coding problems. The coding questions weren't extremely difficult—more medium level overall—but they tested whether you could actually implement something under time pressure. After that screening, I moved on to two technical interview rounds conducted over video. The first technical round focused on my resume and the projects I'd listed. The interviewer asked me to walk through what I'd built, the technologies I used, and the problems I solved. It felt like a genuine conversation rather than an interrogation, which was refreshing. The second technical round dug into Java concepts since that was my main language, along with DBMS and SQL fundamentals. I got questions on things like inner joins and had to explain my approach to structuring SQL queries. The interviewers were genuinely kind and patient throughout—they didn't make me feel rushed or stupid if I had to think through something. After the two technical rounds came an HR round with scenario-based questions about how I'd handle workplace situations. Throughout the process, I was asked about the roles I was interested in on the team and when I could start. One thing I appreciated was that they were transparent about preventing cheating during video calls—they asked me to show the room at the start, which made sense for a remote process. The whole thing felt fairly streamlined. I wasn't waiting weeks between rounds, and the feedback loop was quick. By the end of the final interview, I had a sense of where things stood.
Prep tip from this candidate
Be ready to articulate the projects on your resume in detail—what problem they solved, what tech stack you used, and why you made certain choices. Additionally, drill SQL fundamentals, especially joins and query optimization, since those came up repeatedly across rounds.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report the process opens with a timed online test covering aptitude or verbal reasoning, multiple-choice questions on core CS subjects like DBMS and OS, and one or two coding problems typically rated easy to medium. In one case this was an SHL test. This stage appears to function as a gate before any live interviews are scheduled.
Candidates report live technical rounds focused on data structures and algorithms, sometimes with added constraints such as solving a counting problem without maps, filters, or counter variables. Other reported topics include binary search trees, Fibonacci recursion, stock buy-sell optimization, and fundamentals like OSI layers and TCP versus UDP. Reviewing basic networking alongside DSA may help.
A separate or combined technical round typically covers Java fundamentals such as multithreading, exception handling, and the collections framework. It also includes SQL questions like writing a query for the second-highest salary or explaining inner joins. Candidates describe this round as testing depth of fundamentals rather than obscure or trick questions.
Several candidates describe a round centered on their resume and listed projects, where interviewers ask what was built, which technologies were used, and why certain approaches were chosen. One candidate noted this felt more like a genuine conversation than an interrogation. Another candidate found some unexpected questions, like authentication topics, outside what their resume suggested.
Most reports describe a closing HR round covering strengths, weaknesses, willingness to relocate, and general fit. Some candidates also received scenario-based questions about handling workplace situations. This round is generally described as brief and conversational compared to the earlier technical rounds.
