Summary
I completed a 60‑minute HackerRank assessment for a Wells Fargo internship, which included an anagram coding problem, a SQL query, and an OOP implementation.
How it went
So I had my OA of for internship at Wells Fargo today. There were 3 questions that were asked and I had to complete them in 60 minutes. The test was conducted through HackerRank.
Question 1 (Coding) It was a simple question of anagrams. There were 2 arrays words and phrases. Words contains a list of words in lowercase english letters and phrases contained small sentences without punctuation made from the words in words array. We had to return the number of possbile phrases that can be created by replacing word of each phrase with its all anagrams in the words array. I solved it by creating a hashmap of the sorted words and counted the frequency of each one. Then I simply multiplied the frequency of each word of phrase to get all possible combinations.
Question 2 (Database) I was given 2 schemas, bonds and interest_rates, I had to show the highest interest, avg interest and lowest interest of each bond which had avg interest >3%
Question 3 (Programming) It was more like a simple OOPS question but I had to write the code in an IDE. I had to implement a Students and Course class with basic functions such as get_students, get_courses, disenroll, etc.
Questions asked (3)
- 01
Count Possible Anagram Phrases
Data Structures & Algorithms
Given two arrays:
- words: a list of lowercase English words.
- phrases: an array of small sentences (no punctuation) composed of words from the words array. Return the number of possible phrases that can be created by replacing each word in a phrase with any of its anagrams present in the words array. The solution involves building a hashmap where the key is the sorted form of a word and the value is the frequency of that anagram group. For each phrase, multiply the frequencies of the corresponding word groups to obtain the total combinations.

Bond Interest Statistics Query
Other
Two schemas are provided: bonds and interest_rates. For each bond, retrieve the highest interest rate, the average interest rate, and the lowest interest rate, but only include bonds whose average interest rate is greater than 3%.
- 03
Implement Student and Course Classes
Other
Write code (in an IDE) to implement a Students class and a Course class. The classes should provide basic functionality such as
get_students,get_courses,disenroll, and similar methods to manage the relationship between students and courses.
