Math Basics for Technical Interviews When it comes to technical interviews, having a solid foundation in math is essential. While computer science is often associated with math, the truth is that you typically only need high school-level math for most software engineering interviews and day-to-day job tasks.
LeetCode, a popular coding platform, has over 2000 questions, but it's important to note that just because a math trick or concept is used in some of those questions doesn't mean it's commonly asked in interviews. The top questions asked by companies rarely require advanced math knowledge.
In the rare event that you do encounter a tricky math question during an interview, it's important to remember that the overall evaluation process usually involves multiple engineers reviewing your performance. If a question is deemed too difficult or off-topic, it will likely carry less weight in the final decision.
If you don't remember high school math, don't worry! You can quickly learn or refresh your knowledge in about an hour. Let's start with some basics.
Understanding Number Bases:
Number bases determine the unique digits and the value each position represents in a numeral system. In the decimal (base 10) system, which humans commonly use, there are ten unique digits (0-9), and each position represents an increasing power of 10. In contrast, computers use the binary (base 2) system, where there are only two unique digits (0 and 1), and each position represents an increasing power of 2.
Introduction to Logarithms:
A logarithm is the inverse of an exponential function. It answers the question: To what power must we raise a certain base to get a specific number? Logarithms are often used in computer science because many computational problems naturally split themselves in half.
Sets and Sequences:
In mathematics, a set is a collection of distinct items, while a permutation is a specific arrangement or ordering of the elements in a set. The number of permutations for a set of size n is n!, which is the product of all positive integers less than or equal to n.
Subsets:
A subset of a set contains only the elements that are also present in the original set. The number of subsets a set can have is 2^n, including the empty subset and the set itself.
Arithmetic Sequences:
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant. The sum of an arithmetic sequence can be calculated using the formula: (first-element + last-element) * number-of-elements / 2.
When it comes to technical interviews, having a strong understanding of these math basics will serve you well. Remember, most interview questions focus on coding and problem-solving skills rather than specific math knowledge. So don't stress if you encounter a question that requires advanced math. Focus on your problem-solving abilities and demonstrate your coding skills to succeed in technical interviews.
