Hola! Recently I went for an interview for a DevOps/IT Engineer position at NYC. I was skeptical about my skill set and if I would be able to talk about ‘DevOps’ stuff and etc…
To my surprise, I learned more about myself during that interview. I was able to talk about and respond to about 95% of their questions with confidence. I underestimated myself. I know more that what I thought. This may happen to many. But, I suggest you go out there and apply to jobs with fancy and scary ‘Job titles’.
Go and interview with a mindset of a spy. Ask questions about the technology the company uses, daily tasks, team environment and etc..Don’t be afraid!
Below is the main key points I discussed during the interview with this high-end Advertising company. I’m going over each and reviewing/improving my skills. I hope they can help you also.
AWS: Concentrate on the main services only.
Basic commands to Linux (CentOS/Ubuntu).
Apache virtual hosts.
Load balancer basics.
SSL certificates installs.
OAuth, APIs, OpenID, etc.
Let me know if you have any questions in the comments section. Cheers!
Pick an Open Source project that you like and pick a task. Most open source projects host their repositories on GitHub. One of the great features of GitHub is that each repository comes with an issue tracker – just click the “Issues” link in the left sidebar of any of your favorite repositories to see where you can help. (Ex: jQuery’s issues)
Help prevent email spoofing for outgoing messages. DKIM adds an encrypted signature to the header of all outgoing messages. Email servers that get these messages use DKIM to decrypt the message header, and verify the message was not changed after it was sent.

Set up SPF to prevent spammers from sending unauthorized emails from your domain. This type of spamming is called spoofing. Sender Policy Framework (SPF) is an email security method to prevent spoofing from your domain.
Spoofing is a common unauthorized use of email, so some email servers require SPF. If you don’t set up SPF for your domain, messages could bounce or could be marked as spam.

Set up Domain-based Message Authentication, Reporting, and Conformance (DMARC) by adding policies to your domain’s DNS records. Policies define how your domain handles suspicious emails. Policies are defined in the form of a TXT record.
There are three possible DMARC policies for how your domain responds to suspicious emails:
Take no action on the message and log it in the daily report.
Mark the message as spam and hold it for more processing (quarantine).
Cancel the message so that it is not sent to the recipient.
