Wells Fargo || Technology Summer Analyst 2026 || On-Campus
Summary
I experienced an interview process for the Technology Summer Analyst 2026 role at Wells Fargo, which included an online assessment, two technical rounds covering DSA, OOPs, DBMS, projects, and a final HR/managerial round. The process primarily focused on my problem-solving skills, technical knowledge, and behavioral attributes.
Full Experience
📍 Online Assessment (OA) : The OA consisted of multiple sections with no backtracking (i.e., once a question is opened, you can't revisit it). The structure was:
GenAI-based questions (10): Conceptual and scenario-based questions related to AI and its applications.
Data Interpretation:
Pie charts, bar graphs, and table-based questions
Verbal English section (2 comprehension passages with related MCQs)
DSA Coding (3 Questions):
Easy: Array-based question on computing the square root of a number.
Medium: Longest Common Prefix from a vector/array of strings (return as a string).
Hard: Graph-based question – find an Euler path such that all nodes are visited.
💻 Technical Interview Round 1 (40 -45 Minutes) : Introductory discussion followed by core CS and DSA topics. OOPs Concepts: Inheritance and other basic principles.
DSA Questions: Count frequency of elements in an array. Compare two dates in "dd/mm/yyyy" format and identify the later one.
DSA Theory Questions: What is a HashMap? Is it faster than an array? If yes, why?
DBMS concepts:
Types of Joins Given a scenario, write an SQL Query Design a database and explain keys and their differences Projects & Internship: Questions about your Flutter + Firebase projects Asked how you resolved technical challenges Tools/Technologies used Asked about Java and Spring Boot (I clarified these were not in my resume, and the interviewer was fine with that)
💻 Technical Interview Round 2 (25 -30 Minutes) : Focused on Resume-based Discussion: Projects, internship role, and problem-solving approach Tech stack used: Flutter, Firebase, MongoDB Concepts in JavaScript (especially filters) Play Store Deployment process
DBMS: Indexing: types and real-life use cases What is Flutter? Why use it? Flutter UI (widgets, layouts, responsiveness)
💬 HR + Managerial Round Behavioral and situational questions
Focus on: Team collaboration Handling failure Decision-making in critical scenarios
