rtCamp Interview Experience for Devops Engineer

The rtCamp is a Pune-based organization that mainly works on WordPress. I applied for the position of DevOps Engineer at this organization through their careers site.

As a first step after applying, I received an email from them stating that my resume was selected, and they provided an assignment link with a flexible deadline.

Assignment:  The assignment required me to perform the following tasks: https://rtcamp.com/assignments/devops-engineer/

I completed the assignment and submitted the work link through the mail.

Technical Interview: After that my technical interview was scheduled, which took place on Zoom. During the interview, I was asked the following questions:

• Can we use Git without GitHub?
• What is the difference between Git and GitHub?
• Where does Git store data?
• Is basic email registration through JavaScript sufficient for security purposes? What are the alternatives?
• Explain the difference between sessions and cookies.
• Can we use sessions without cookies?
• Define encryption and hashing.
• What is salt in hashing?
• Suppose your site is experiencing high traffic, causing lag. How would you manage it to reduce server load?
• Explain horizontal and vertical scaling.
• In Linux, how can you check which process or application is consuming the most storage/memory and how can you remove it?
• How do you terminate a running process?
• Which process is utilizing the most resources?
• What is a Docker volume?
• Differentiate between an image and a container in Docker.
• How would you take backups of your servers?

These were the questions asked during the interview. At the end, the interviewer allowed me to ask any questions I had.

Tip:  During the interview, it is important to answer confidently and be prepared for questions related to your profile. Ensure you have a deep understanding of fundamental concepts in both development and operations

If you have directly landed here, and have questions about this whole “assignment” thing, you may  read this first !

Now you are settled, the purpose of this assignment is to check if you can write the quality Laravel code.

Assignment Alternatives

If you have existing work samples to show and you missed submitting them during the application process, you can still submit them by replying to the email you receive upon your application.

• We accept any link where we can see your source code in a version control environment such as WordPress.org, Github, Gitlab, Bitbucket.
• Link to one or more git/svn commits in case you do not have a solo project to show but have a significant contribution to a larger project where we can see your code commits.

Not Acceptable

• Sending links to public sites! It doesn’t tell us anything about your code quality or if you have followed coding standards or written test cases.
• Sending zip files either as an attachment or via dropbox or some public link. Zip files do not give us visibility into your commit history over the time which tells a lot about how disciplined you are!

As we attract people from different walks of life, we have many options to suit everyone’s needs, tastes, and experiences here. So please carefully read every scenario described below and pick the one as per your comfort, you can always reach out to our hiring team for further clarification.

Irrespective of which challenge you choose, please note down our common minimum requirements applicable to all challenges.

• Responsive – Your code must work on mobile devices like iPhone/Android.
• Code Organisation – All 3rd party codes, libraries must be inside vendor folder. No unwanted files e.g. IDE files, temporary files should be committed on git-repo.  (Hint: Write a nice .gitignore)
• Coding Standard – Your code must adhere to PSR-2 coding standard and the PSR-4 autoloading standard. Additionally, you can configure  scrutinizer-ci  so your code quality can be seen easily.
• Unit Testing – Having unit tests for the code you write will be a plus point. You may use  php artisan make:test ExampleTest  to create a unit test for an Example class.
• Github Readme – Write a nice Github Readme using markdown syntax. Make sure you include a demo link and links to libraries used in the readme.
