Coderpad interviews are a popular way for companies to assess the coding skills of job candidates. Coderpad interviews involve a real- time code writing and testing session conducted over the internet. The interviewer will present the candidate with a coding challenge or project and then the candidate will attempt to solve it in the allotted time. The interviewer is typically able to view the candidate’s code in real- time, while they are coding.
The candidate is also able to see the output of their code as they work, which allows them to make sure that their code is producing the expected results. During the course of the interview, the interviewer will ask questions about the code that the candidate has written and the reasoning behind their decisions. This allows the interviewer to gain insight into the candidate’s coding skills, problem- solving abilities, and their thought process.
At the end of the interview, the interviewer will usually ask the candidate to explain their code and the reasoning behind it. They may also ask the candidate to explain how they would improve their code or go about solving a similar problem. This allows the interviewer to get a better understanding of the candidate’s programming experience and their ability to think critically.
Coderpad interviews involve a lot of back and forth between the interviewer and the candidate. It is important for the candidate to stay organized and clearly explain their thought process to the interviewer. By doing so, the candidate can demonstrate their coding skills and problem- solving abilities and stand out from other candidates.
