Interview Preparation Tips
- Coding: The person interviewing you wants to see how you solve a problem with structured and useful code.
- Say what you’re thinking out loud. For example, “Let’s try this way—not sure if it will work yet.” Just putting into words what’s on your mind can help you get unstuck. Spell out what might be effective. Explain the first thing you thought might work and the reason it doesn’t. This is also true for questions that are just meant to be fun small talk. If someone tests your knowledge of JavaScript closures, saying “It has to do with scope and putting something in a function” will probably get you 90% of the points possible.
- Just admit that you dont know anything. If you’re only going to briefly mention a fact (like a piece of language-specific trivia or a small piece of runtime analysis), don’t make it sound like you know more than you do. Say something like, “I’m not sure, but I think something because ” rather than “I dont know. As for the “because,” it could mean ruling out other options by showing that they make no sense, using examples from other languages or other problems, or any mix of these three.
- Create pictures with a pencil. Think about something on the board instead of trying to think of it in your head, which will waste time. Build a few unique test inputs and compare their results. Make a diagram that shows how you would reach your goal using only hard work. The next step is to think about how your plan could be put into action using code. Discover a much simpler way to solve the issue at hand. Are you having trouble finding the fourth largest piece in the collection? If so, what is it? Think about how you found the first item based on its size and see if you can change your approach.
- In order to solve the problem, you should first write down a simple, bad answer. Then, you can improve it later. Use brute force. Do everything that needs to be done to get some kind of response.
- Hold your breath and wait for a hint. Do not look at your interviewer expectantly, but do take a moment to “think.” Your interviewer may already have an idea for what to say and is just waiting for you to finish before speaking. You might be getting a hint from your interviewer if you look at them expectantly. They may be waiting to avoid interrupting you so they can give you the hint.
- Optimizations: Think about the limits that the runtime and the available space put on you. If you’re not sure if your solution can be improved, say it out loud to yourself.
What is IPC communications?
When other processes run, they don’t affect an independent process. But when other processes run, they can affect a cooperating process. One might think that processes that work on their own will be quick, easy, and modular, but cooperative behavior can actually be used to make computations faster, easier, and more modular. Inter-process communication, also written as IPC, is a way for processes to talk to each other and make sure that their actions are coordinated. Cooperation between these processes is accomplished through this communication.
