How to prepare more quickly for coding interviews — Coding interviews are getting harder every day. A few years back, brushing up on key data structures and going through 50–75 practice coding interview questions was more than enough prep for an interview. Today, everyone has access to massive sets of coding problems, and they’ve gotten more difficult as well…

Stand out from the crowd with these coding interview secrets! Coding interviews are getting tougher every day. Now that everyone has access to hundreds of coding questions and can spend a lot of time preparing for the coding interviews, it has become quite difficult to stand out from the crowd. …

What is CAP theorem and how does PACELC extend it? — In distributed systems, different types of failures can occur, e.g., servers can crash or fail permanently, disks can go bad resulting in data losses, or network connection can be lost, making a part of the system inaccessible. How can a distributed system model itself to get the maximum benefits out…

While designing a scalable system, one of the most important aspects is defining how the data will be partitioned and replicated across servers. Let’s first define partitioning and replication so that we are on the same page. Data partitioning: It is the process of distributing data across a set of…

Up your game solving coding questions with these three techniques — Binary search, as we all know, is the easiest difficult algorithm to get right. It is also one of the smartest searching algorithms with a guaranteed running time of O(logN) for an input array containing N sorted elements. In this post, I will share three smart modifications of the binary…
