Visa Software Engineer Phone Screening

Overview: The phone screening is the initial step after recruiters review your resume to ensure you meet the minimum qualifications for the position. This 30 to 45-minute conversation focuses on your work experience, educational background, and technical skills. Be prepared to discuss your motivations for applying, and highlight your accomplishments and skills clearly and concisely.

Visa Software Engineer Online Coding Assessment

Overview: The Online Assessment (OA) is designed to evaluate your coding abilities and problem-solving skills. Conducted on CodeSignal, it may also be administered as a take-home assignment. The OA typically includes HackerRank-style questions that test your proficiency in programming languages like Java, Python, or C++. You will be given a specific timeframe to complete these tasks. A preview candidate reported receiving a coding assessment with four LeetCode-style questions.

Prepare effectively for Visa’s software engineering interview process by understanding these key stages and focusing on relevant technical skills and experience.

In Visa’s Software Engineer interview process, you will undergo two 30-minute technical interviews with senior engineers.

First Technical Interview: The initial technical interview features standard software engineering questions. Expect to solve four LeetCode medium-level problems on topics such as binary search, trees, stacks, queues, and arrays. You will have about sixty minutes to complete this round.

Second Technical Interview: The second technical interview focuses on development problems across various topics, further assessing your coding and problem-solving skills.

Prepare for Visa’s technical interviews by practicing relevant coding problems and familiarizing yourself with common data structures and algorithms.
