Personally, I prefer to review as I practice, so I scan through my college notes and review the various algorithms as I work on algorithm problems from LeetCode.

While "Cracking the Coding Interview" is a good resource for studying, I prefer being able to type code, run it and get instant feedback. There are various Online Judges such as [LeetCode](https://leetcode.com/), [HackerRank](https://www.hackerrank.com/) and [CodeForces](http://codeforces.com/) for you to practice questions online and get used to the language. From experience, LeetCode questions are the most similar to the kind of questions being asked in interviews whereas HackerRank and CodeForces questions resemble competitive programming questions. If you practice enough LeetCode questions, there is a good chance that you would have seen/done your actual interview question (or some variant) on LeetCode before. - -If you are more of a visual person, [Coderust](https://www.educative.io/collection/5642554087309312/5679846214598656?aff=x23W) explains the common algorithm questions through step-by-step visualizations which makes understanding the solutions much easier. - -### Broaden exposure - -Gain a broad exposure to questions from various topics. If you can spare the time, do around 100–200 LeetCode questions of varying topics and you should be good. If you are short on time or not sure where to start, the [Best practice questions](./best-practice-questions.md) page recommends you the best 50 LeetCode questions to practice. - -### Identify question patterns - -As of writing, LeetCode has thousands of questions available. Which should you practice? It is not a good use of time to practice too many questions as after a while, you will realize that some questions are variants of one another and involve using similar techniques you've seen before. The trick here is to identify the question pattern and techniques you can use to solve variants of this question. Once you're familiar with a pattern, you'll be able to solve dozens of similar problems. Some techniques include - sliding window, two pointers, matrix traversal. The ["Grokking the Coding Interview: Patterns for Coding Questions" course on Educative](https://www.educative.io/courses/grokking-the-coding-interview?aff=x23W) shows you even more techniques and is highly recommended. - -:::tip Expert tip - -Learn and understand patterns, not memorize answers! - -::: - -### Space/time complexities - -Learn and understand the time and space complexities of the common operations in your chosen language. For Python, this [page](https://wiki.python.org/moin/TimeComplexity) will come in handy. Also find out the underlying sorting algorithm that is being used in the language's `sort()` function and its time and space complexity (e.g. in Python it's Timsort, which is a hybrid sort). After completing a question on LeetCode, I usually add the time and space complexities of the written code as comments above the function body to remind myself to analyze the algorithm after I am done with the implementation. - -### Practice good coding style - -Read up on the recommended coding style for your language and stick to it. If you have chosen Python, refer to the [PEP 8 Style Guide](https://www.python.org/dev/peps/pep-0008/). If you have chosen Java, refer to [Google's Java Style Guide](https://google.github.io/styleguide/javaguide.html). - -### Internalize language pitfalls - -Find out and be familiar with the common pitfalls and caveats of the language. If you point them out during the interview and intelligently avoid falling into them, you will usually impress the interviewer and that results in bonus points for your feedback, regardless of whether the interviewer is familiar with the language or not. - -:::tip - -The key to interview success is practice, practice and more practice! - -::: - -## External resources - -- This [interviews repository](https://github.com/kdn251/interviews) by Kevin Naughton Jr. served as a quick refresher for me. -- The Medium publication [basecs](https://medium.com/basecs) by [Vaidehi Joshi](https://medium.com/@vaidehijoshi) is also a great and light-hearted resource to recap on the various data structures and algorithms. -- You can also find implementations of common data structures and algorithms using various popular languages at [TheAlgorithms](https://thealgorithms.github.io/). diff --git a/website/blog/2021-08-30-a-glimpse-into-front-end-interviews.md b/website/blog/2021-08-30-a-glimpse-into-front-end-interviews.md index 823d4e82..b454ea7d 100644 --- a/website/blog/2021-08-30-a-glimpse-into-front-end-interviews.md +++ b/website/blog/2021-08-30-a-glimpse-into-front-end-interviews.md @@ -14,7 +14,7 @@ A glimpse into the front end interview process and questions that frequently com - + ## Interview Process diff --git a/website/src/pages/index.js b/website/src/pages/index.js index ea41ff97..3cf316df 100755 --- a/website/src/pages/index.js +++ b/website/src/pages/index.js @@ -520,7 +520,7 @@ function TweetsSection() { handle="Insharamin" name="Insha" date="Jul 8, 2021" - avatar="https://pbs.twimg.com/profile_images/1468474545891774464/jENKPsRG_400x400.jpg" + avatar="https://pbs.twimg.com/profile_images/1513932354552619009/w5MTxjG2_400x400.jpg" content={ <> 1️⃣ Tech Interview Handbook
