Good Platforms and Communities for DSA and System Design Mock Interviews

Hello folks!

As many of you know, preparing for interviews at top tech companies like FAANG (Facebook, Apple, Amazon, Netflix, Google) can be a daunting process, especially when it comes to mastering Data Structures and Algorithms (DSA) and System Design. Mock interviews play a crucial role in this preparation, providing a safe space to practice and receive feedback.

The Need for Affordable Mock Interviews

While there are many platforms available, such as Exponent and Pramp, the costs can often be prohibitive. For those of us preparing on a budget, finding affordable or even free options is essential. Below, I’ve compiled a list of resources that may help you in your journey to nail those interviews without breaking the bank.

1. LeetCode

LeetCode is well-known for its extensive collection of coding problems that can help you prepare for technical interviews. While it doesn’t provide mock interviews per se, you can use its discuss section to find peers who are also preparing and might be open to conducting mock interviews with you.

2. Interviewing.io

This platform allows you to practice live technical interviews with engineers from top tech companies, including FAANG. The best part? It’s completely free! You can also get feedback on your performance, making it an excellent resource for improvement.

3. Pramp (Free tier)

Although you mentioned Pramp is costly, it actually offers a free tier where you can conduct peer-to-peer mock interviews. While it might not have as many features as the paid version, it’s a great way to get started without spending a dime.

4. Discord and Slack Communities

There are several Discord and Slack communities dedicated to interview preparation. Examples include “Tech Interview Prep” and “FAANG Interview Prep.” These communities often have members who are also preparing for interviews and are open to conducting mock sessions.

5. YouTube Channels

Many YouTube channels focus on interview preparation, and some experienced professionals offer mock interviews or tips on how to conduct them effectively. Channels like “TechLead” and “CS Dojo” might have valuable insights and mock sessions that you can learn from.

6. LinkedIn

Consider reaching out to professionals on LinkedIn who are currently working at FAANG companies. Many are willing to help out by conducting mock interviews for a reasonable fee or even for free in exchange for mentorship or networking opportunities.

7. Local Meetups and Study Groups

Check platforms like Meetup.com for local groups focused on interview preparation or coding challenges. These groups often host sessions where you can practice with peers in a supportive environment.

8. GitHub Repositories

There are numerous repositories on GitHub where contributors share their interview experiences, coding challenges, and even frameworks for conducting mock interviews. Searching for “mock interview prep” or similar keywords can yield useful resources.

Conclusion

Preparing for FAANG interviews doesn’t have to be costly. By leveraging the resources mentioned above, you can effectively practice DSA and System Design mock interviews without stretching your budget. Remember that the key to success is consistent practice and seeking constructive feedback.
