Data Structures And Algorithms Q&A and Videos

I am a seasoned Mobile engineer(Staff+) and have been looking for a new job since this January.

After failing at several job interviews with big tech companies like Meta, Square, Airbnb, Uber, etc I finally received offers from Okx, Doordash and Reddit.

To be honest, I feel like the biggest gap was DS&A. Over time, I improved a lot in this area and through the help of mentors and referrals, I was able to land the above offers. I'm very grateful for Taro (especially Rahul) for his constant words of encouragement and his guidance when I needed his help.

To everyone out there, I know the market may seem crazy but if you weather the storm, you will find success. If I can do it, you can too! Good luck!

Both in the context of a data structure and algorithm problem and in the context of a software problem or any problem really it is important to weigh the pros and cons and have arguments to back your decision making.

Having the knowledge to come up with several solutions is challenging - how do you get good at this? Is experience the only answer? Do you have any techniques you put in place to help with this?

I’m currently working as a Data Engineer for a mid-sized (1500 people) investment-services corporation. The company has been around for a long time and makes money, but it definitely isn’t a tech-first company (e.g. it refers to the software side as “I.T.”, has tons of meetings, approvals needed to install almost anything on my computer, including VSCode).

I want to get into FAANG as a software engineer because I want to move away from the business/data side of things and closer to the engineer side of things. On my current team, I’m the lone data-engineer (will be joined by another in a few months) and as someone with <3 years of experience, I know that my growth is being stunted.

I’m currently grinding AlgoExpert to prep for interviews.

How should I think about the circumstances under which it would be worthwhile to quit in order to prep (full time) for FAANG interviews? Here’s what I can come up with in terms of current pros/cons of quitting:

Pro’s of quitting:

• A LOT more time to prep for interviews, can probably increase my output of questions by 3x
• Can do a lot more interviews without worrying about my job and scheduling
• Do less business/data stuff which I plan on moving away from anyways
• Get closer to a FAANG salary faster, which will likely be around 2x of my current salary

Cons:

• Don’t know how long it will take me to get a job
• Don’t know how easy it will be for me to get interviews without a job
• Psychological benefits of having a job
• Some learning on the job
• Low-stress job, nice manager, no overtime
• Already take an hour or two of my current job time to do AlgoExpert
• Make some money right now

How does the answer change (if at all) if I manage to land interviews with a bunch of different FAANG companies (say 5+) and I’m struggling to schedule all the time for interviews, prep for them, and do minimal work at my current job?

Thoughts are appreciated!

I am a senior engineer and would like to get in to MAANG, but I'm rusty in DS. I don't want to give interviews to MAANG companies until I figure that out Are there any power patterns to start with? And what would be the good starting point to solve problems? I am looking for a smart way to achieve this.

In reality most of the Fortune 500 companies I worked in the past, they never dig too much in DS problems. Most care about system design and knowledge about code.

I see few people mentioning solving 200+ problems in LeetCode which is a lot of time consuming process. I'm trying to find answers from few people who already went through this.
