I gave the interview for position of Sr. Software Engineer (Fullstack, Java & Angular) at Visa.
Round 1 (Part A)
1. Angular basic building blocks
2. How will you show a bar graph of a data from past 100 years data receiving from Backend.
\tInterviewer wanted to see how I\'ll approach the problem but not the actual code
3. Authentication & Authorization in your frontend.
4. Basic components of NgRx store (was written in my resume)
5. How did I migrate from Angular v8 to v13 (was written in my resume) (Exact command)
6. How can send data between two components in angular
\ta. Parent to Child (Ans. @Input decorator)
\tb. Child to Parent (Ans. @ViewChild decorator, also use ngAfterViewInit)
\tc. Unrelated Components (Ans. Create a Service)
7. Write a piece of code for subscribing an observable from an API Call and handle error
8. Print the subset with sum k.
Round 1 could not be completed within 1 hour so another part was scheduled for next day
Round 1 (Part B)
1. Functional interface
2. Will functional Interface work without annotation
3. Can Interface have function def.
\tAnd No
4. Stream API is built on top of collections interface but interface don\'t have function definition. How java overcame this?
\tAns: default functions
5. How to intercept all request and responses from a Springboot app
\tAns: interface
6. Spring Security features.
7. Use of Repository annotation
8. If we have two implementation of an interface and use @Autowired for the base interface object, will aplication run ?
\tAns No.
9. How can you make this work?
\tAns @Qualifier annotation
10. Checked & Unchecked Exception in java with example
11. You are given two arrays. One of the arrays has some number missing. Print the missing numbers.
Verdict Not Selected
Got a call from recruiter after 3 weeks that positionis already filled but since you had good feedback we have another opening from backend role if interested. But will have to give round 1 again.

About Visa Interview Reports
This question was reported by a candidate who interviewed at Visa. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Visa are the higher-signal extractions to take from this report.
For broader preparation context, the Visa interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Visa reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Visa Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Visa reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
