In the North American IT job search, algorithmic ability is the focus of the examination. Many well-known technology companies, such as Google, Facebook, Amazon and others, make algorithms and data structures the core of the interview. Therefore, by practicing, you can not only improve algorithmic thinking but also improve the chance of getting an Offer.
First of all, we should develop a reasonable training plan. Algorithm learning is a step-by-step process. Beginners can start with basic data structures and common algorithms, such as groups of numbers, linked lists, stacks, queues, hash tables, binary search, sorting algorithms, etc. Later, you can delve into advanced content such as dynamic programming, graph algorithms, and backtracking algorithms. For beginners, LeetCode, CodeSignal, HackerRank and other platforms are recommended, combining Easy, Medium and Hard difficulty questions to gradually improve.
Secondly, master efficient brushing methods. It's easy to get half the result with half the effort, so it's recommended to follow these steps:
1. Do not rush to start, but carefully read the topic, clear input and output, and constraints.
2. Don't look at the answer directly, but try to think of different solutions for yourself, and analyze the time and space complexity.
3. Try to implement with your own code to ensure that the code structure is clear and the variable naming is standard.
4. If the initial code efficiency is not high, you can think about whether there is a better solution, such as the use of dynamic programming, caching and other optimization means.
5. After brushing the problem, record the problem-solving ideas and common pits to ensure that similar problems can be quickly solved next time.
In addition, it is important to conduct simulation training in conjunction with the interview situation. In interviews, algorithmic questions often require coding in the field in a whiteboard or online editor, so you need to train yourself to solve problems within a limited timeframe and be able to articulate ideas. You can team up with friends to conduct mock interviews or use platforms such as Pramp and Interviewing.io for practice.
Finally, in addition to algorithm brushing, you should also pay attention to basic computer knowledge, such as operating systems, databases, networks, etc. Many large companies will test the comprehensive ability of the interview, so the algorithm and computer foundation should be equal. In addition, maintaining a good attitude, facing the challenges in the interview, calmly analyzing the problem, and constantly improving are the key to getting the Offer.
Through scientific and reasonable brush methods, combined with actual interview training, job seekers can greatly improve their algorithmic ability and problem-solving skills, to stand out in the technical interview and successfully get the ideal Offer.
