Wells Fargo Interview Experience for Internship

DAY 1 – Online Test:

It consisted of 3 sections :  

• English: Easy grammar and vocabulary questions, replacing a word and passage-based questions.
• Business: Pretty lengthy Graph-based questions on stocks, shares, and case studies
• Coding: There were 2 questions. One of them was Count number of bits to be flipped to convert A to B

DAY 2 – Technical Interview: It was a 45-min round held on Zoom call. I was first asked to give a brief academic introduction and state my weaknesses. Then a few technical questions including:

1. The complete concept of Object-Oriented Programming
2. Mechanism of Multiple Inheritance
3. Difference between interface and abstract class
4. DBMS conceptual questions
5. Difference between inner join and outer join
6. Normalization in DBMS

Then I was given 2 array questions to code. I had a choice to opt for any IDE I was comfortable with. In the end, I was asked if I had any questions for the interviewer.

Managerial Interview: This was a 30-min round. I was told to brief about my resume and experiences after which I was asked questions on application and website development. A few topics in tree and graph data structures and memory management were also asked. The round ended with some DBMS related technical questions.  

A few of them are:

1. Difference between structured and unstructured databases
2. What does an application’s vulnerability mean?
3. Explain the stability and resilience of an application
4. What is a developer’s part in making a robust application?
5. How can 2 or more applications or websites interact
6. Explanation about web servers

This round was difficult compared to the previous interview round but I managed to keep up the pace with the harder questions with whatever basic knowledge I had about them.

HR Round: It was quite a brief non-technical round. It started with a 2-min introduction. Then I was then asked about my strengths, weaknesses, and a few questions on my resume. It was basically a screening of my confidence level and communication skills.

This was the end of my interview process. A few hours later I was informed that I was selected for the internship.
