Types of Problems
Leetcode contains a diverse set of problems from different problem categories. These problems help interviewees prepare for their interviews by testing their algorithm and data structure knowledge. Currently, there are eighteen different categories that an interviwer could test your knowledge in. In no particular order, these are: Arrays, Two Pointers, Stack, Binary Search, Sliding Window, Linked List, Trees, Tries, Backtracking, Heaps/Priority Queues, Graphs, Dynamic Programming, Intervals, Greedy Algorithms, Bit Manipulation, and Math/Geometry.

In each problem category, there are three levels that a problem could be: easy, medium, and hard. If you are applying for an internship concurrently pursuing your undergraduate degree, then you will most likely encounter easy and medium questions - very rarely, will you be asked a hard leetcode question. If you are applying for a new-graduate offer - meaning that you previously graduated, and you want to work at a company - then you will be asked questions in the medium and hard range. There are 736 easy questions, 1521 medium questions, and 634 hard questions.

When Are You Ready To Interview
Leetcode questions are created to challenge your brain. It can take months before you are ready to start interviewing. Most applicants will be pursuing their undergraduate degree, so they will be concurrently preparing for interviews with leetcode during those four years. In the case that you are not pursuing your undergraduate degree, self-preparation can take months to complete. Leetcode offers monthly study plans to ensure that your brain has all the knowledge it needs to solve any problem an interviewer may give you. Additionally, Leetcode offers an online interview preparation IDE (Integrated Development Environment). In this IDE, you and someone else can take the part of the interviewer and interviewee and prepare for interviews with your friends and colleagues. Furthermore, if someone wants to gauge their overall performance in an interview at any particular moment in time, they can instantiate an Leetcode-style online interview. In this online interview, a timer of one-hour and thirty-minutes is started, and three questions are given. The difficulty of each question is hidden, just as in an actual interview. If someone wants specific questions from a company that they are soon interviewing for, then Leetcode offers a paid subscription and users can identify which company they want their questions to be chosen from. For example, if someone choose Google as their online interview, then Leetcode will only give them questions that Google has asked application from previous interview cycles. Once you have solved multiple questions from real online Leetcode-style interviews, then that is when you know you are ready to start interviewing.

The Interview Process
Depending on which company you are applying for, the amount of leetcode-style assessments that you will encounter can vary from one to five. For example, Google requires applicants to code through a series of five assessments. Three of these assessments are online, while two of them are whiteboard interviews.

Below are the processes that a candidate must follow to enter into the software engineering industry or the quant developer industry. Both positions are highly lucrative and require a great amount of skill.

The Software Engineering Process The process to become a software engineer is straightforward. Once you apply, you will be sent an online assessment. This online assessment is not proctored, and it will give applicants their first chance to break into a company. Once an applicant passes the online assessment, they will either be rejected or accepted to take proctored interviews. Proctored interviews typically last anywhere from forty-five minutes to one-hour. In this time, a candidate will be given two Leetcode questions. If the candiate is able to answer both of the questions, then he/she will move on to the next round of interviews. Each company has their own standard for the amount of interviews a candidate must pass before they are offered a position. These interviews can be done in any language that you like. The most typical languages are Python, Java, and C++. You can choose Python for its easy readability and syntax. Data structures in Python are easy to create; however, using them can be a little harder. For example, viewing a stack in a list is not usual. You can choose Java because that was the first language you might have learned at your university. In some circumstances, some jobs will require you to apply with C++. C++ is a fast low-level language that works really close to the hardware. For typical software engineering positions, you won't be working on code that is used that closely to hardware, so the choice of language is ambiguous. However, for positions where you are doing something specific, such as working on low-level systems, C++ is often the best choice.

Once a candidate makes it to a certain level of interviewing, he/she may be asked to complete an onsite interview. An onsite interview takes place at the company headquarters, and the candidate transitions from coding in an IDE to the whiteboard, where he/she will write their solution directly in front of engineers who currently work at that company.
