DSA prep for interview

I have 6 YOE as QA. First 3 years I was into manual testing and now since past 3 years, I am an SDET with tech stack- python, pytest , playwright, selenium. I am planning for the job switch now. I have not used much of DSA in my work. However I understand DSA is a must to clear interviews. I need help in preparation. From where and How to start the preparation? Please update your strategies , so that it will be helpful for all those preparing for interviews.

Hi, I'm a software engineer with close to 6 YOE. This is my second company and I feel pretty stagnant here working for 3 years and see no growth. I've started preparing. Is DSA still being asked in the interviews even for people with experience ? How many rounds are there usually and what is being tested? Your advice would be very much appreciated :)

I'm a backend engineer with 6+ YoE. I have never had interest in solving DSA problems. I started off as being very bad at it- I did understand the technical details behind various data structures and algorithms, but never had that passion about applying it to various leetcode problems. Over time, I have got better with DSA, but I still can't say I am at a great level- I still often struggle with Leetcode-medium problems. I am confident of being a decent engineer- with a nice mix of tech and soft skills and an interest in building things. I also have some aspiration of joining a Faang company (or other such top-level company); but I feel overwhelmed at how "good" it requires you to be in DSA. So, I wish to know- how good do I need to be at DSA before I can realistically apply at such companies, given my YoE. And, how may I possibly gauge how far away I still am from that "required level"?

I am a full stack developer with 2.5 years of experience currently working at a global MNV. My current skill set includes java, angular, spring boot framework. I am planning for a switch. I read on the internet that to crack a MAANG or some company of that level you need to have a good understanding of Data Structures and Algorithms(DSA). How to start with DSA preparation. I see there are a lot of resources. I feel overwhelmed by seeing all of them. Are there any good structured courses which teach DSA.

I am a Golang Developer, with around 3yr of experience. Previously, in college, I have practiced DSA in C++. Also, I knew some Java which I used while learning OOPS(LLD) in college. Now since I am considering to switch, I need to revise and practice DSA again. For the last 3 years I have not touched C++ or Java and I love working in Golang. But, now I am in a dilemma. Question: Should I try to relearn the syntaxes of C++ for DSA? Question: For LLD, since Golang does not support “pure” object oriented programming, should I try to practice those in Java? Question: Will it be worth the effort to relearn the syntaxes for the languages I did not use for a long while, for interview preparations?

Hey I joined infosys in oct - 2022 and now it’s been 1.8 months. My tech stack is MEAN stack but I was on bench through the year, recently got into a project but for only 4 months. I developed and learned by my own and gained a better knowledge on angular. Now the situation my company has made for me that I need to switch asap, within a month or two. Can anyone suggest me how to prep specifically so that I get offers from other company. My DSA skills are gone and feel like I need to learn again from basics. I have knowledge about angular. Can anyone suggest me how much DSA I should learn and focus right now to clear interviews. I’m planning to get a grasp over python and start doing DSA questions in that plus polishing my angular skills too. I have basic knowledge of node.js MongoDb too. Will I’ll be able to switch within this time frame? Please can anyone guide me through it so that I can plan smartly and can switch. Your help will be really appreciated.

I am a front end developer with a workex of 2.5 years. I am planning for a switch. I am not good at DSA. I have heard that to get a job at a big company you need to have a strong hold on DSA. What are some of the best resources to start DSA prep?

I’m a college grad from IIT in CSE. I haven’t done any competitive coding or any proper coding during my college days for that matter. I have lost confidence in myself for some reason. I had taken up a business job but left it in a few months because I thought I could do better. I want to do competitive coding but as soon as I open my laptop, anxiety kicks in. I need guidance on how to proceed and what recourses should I use. I don’t want to waste my degree as I feel I can do better than my previous job. Please help me on fighting my demons.

I am preparing for a SDE-2 role in a product based company. There are many online blogs that tells me what to prepare but I am looking out from where I can learn all of these things. DSA - ? LLD - ? HLD - ? Also let me know in the comments if you are also preparing for a switch in SDE-2 roles. 🥷
