Technical Interview, Coding Interview Special Edition

5 min readSep 9, 2022


The next edition this month is about my favorite topic : machine learning and data science. We really are proud of the median tutorial (four ways to find median of sorted array problem). It’s awesome! [public] tips are public, any one can view them. [pro] tips are for paid members of our website only.

Getting ready for your technical interviews. Technical interview preps and developer tips, special edition. WARNING: please read our disclaimer and terms of services first. An excerpt is linked below.

Technical Interview Basics:

Core skills: Programming experiences and skills, problem solving skills, analytical skills, familiarity with technical interview basics such as data structure and algorithms. Data Structure and Algorithms questions are popular among big tech companies like the FANG companies (Facebook, Apple, Airbnb, Netflix, Google). Supposedly only 2% of candidates gets a job at Google. That’s an acceptance rate lower than Harvard and Stanford.

Many career coaches find that reaching out to contacts in your network, and always be networking can really help improve your career search results. There are rumors that internal referrals work well at big FANG companies. It kind of makes sense if we think about it : team work, collaborations are very important at big tech companies. People work well with their friends, and friend groups of brilliant engineers can potentially have higher concentration of brilliant engineers. (If you are good at board games, you can really attract some attention at big tech companies. It’s a serious hobby.)

Alternative career track candidates are now accepted at major companies such as Google, Meta, and JPMorgan. The only obstacle for candidates right now is the terrible trend of layoff. Before the recent disastrous layoff trend, companies like META was providing returnship opportunities for women to re-enter the workforce.

Talking about layoff: Did you hear about the Great Layoff? The new disastrous trend of tech layoffs. It is a good time to brush up on your interview skills, keeping them fresh. This is a sign and motivation to brush up on your skills. Track layoff data using this tracker below.

Data Structure

Working as a real software engineer, chances are you will have to design your own complex, custom data structure sooner or later. Data Structure and Algorithms are the bread and butter of technical coding interviews. These data structures are building blocks of custom, complex data structures. Algorithms are step by step instructions / recipes to complete a task.

Advanced Algorithm Calculating Median

Calculating Median seems like a simple task but it can test advanced algorithm optimization skills, and critical thinking of developers. Median interview questions are popular at Google. There are at least four interesting ways to calculate the median of sorted sub-arrays — small segments of equal length or different length sorted arrays. Find the median of two sorted array is a simplified version of this problem. See our fibonacci sequence tutorial above why we need fancier algorithms to calculate statistics. The answer is big data. When data volumes are high, trivial calculations become non-trivial.
