Interview preparation and interview questions for DevOps and SRE

I have compiled a small ebook for DevOps and SRE preparation. This book is based on rounds that can happen in a DevOps or SRE interview at companies like LinkedIn, Atlassian, Visa, etc. It has below chapters that will help you understand each round and how to approach it.

1. Linux Questions

2. Cloud Specific questions

3. Python programming

4. System design round and how to approach it.

5. Incident management.

6. Basic system Troubleshooting.

7. How to do code reviews.

These are motivated by interview round that happens in big companies that are hiring SRE and DevOps.

I hope this will help you. Feedbacks are welcome.

Thanks to Rahul Sinha for his contribution. hashtag

BunkerWeb - The open-source and next-gen Web Application Firewall (WAF)

BunkerWeb is a next-generation and open-source Web Application Firewall (WAF).

Being a full-featured web server (based on [NGINX](https://nginx.org/) under the hood), it will protect your web services to make them "secure by default". BunkerWeb integrates seamlessly into your existing environments ([Linux](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#linux), [Docker](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#docker), [Swarm](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#swarm), [Kubernetes](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#kubernetes), …) and is fully configurable (don't panic, there is an [awesome web UI](https://docs.bunkerweb.io/1.5.9/web-ui/?utm_campaign=self&utm_source=github) if you don't like the CLI) to meet your own use-cases . In other words, cybersecurity is no more a hassle.

BunkerWeb contains primary [security features](https://docs.bunkerweb.io/1.5.9/security-tuning/?utm_campaign=self&utm_source=github) as part of the core but can be easily extended with additional ones thanks to a [plugin system](https://docs.bunkerweb.io/1.5.9/plugins/?utm_campaign=self&utm_source=github).
