</summary><br><b>

This is the TTL. When you lookup for an address using a domain/host name, your OS is performing DNS resolution by contacting DNS name servers to get the IP address of the host/domain you are looking for.<br>
When you get a reply, this reply in cached in your OS for a certain period of time. This is period of time is also known as TTL and this is the meaning of 3515 number - it will be cached for 3515 seconds before removed from the cache and during that period of time, you'll get the value from the cache instead of asking DNS name servers for the address again.

## HR

These are not DevOps related questions as you probably noticed, but since they are part of the DevOps interview process I've decided it might be good to keep them

<details>
<summary>Tell us little bit about yourself</summary><br><b>
</b></details>

<details>
<summary>Tell me about your last big project/task you worked on</summary><br><b>
</b></details>

<details>
<summary>What was most challenging part in the project you worked on?</summary><br><b>
</b></details>

<details>
<summary>How did you hear about us?</summary><br><b>

Tell them how did you hear about them :D
Relax, there is no wrong or right answer here...I think.
</b></details>

<details>
<summary>How would you describe a good leadership?</summary><br><b>
</b></details>

<details>
<summary>Describe yourself in one word</summary><br><b>
</b></details>

<details>
<summary>Tell me about a time where you didn't agree on an implementation</summary><br><b>
</b></details>

<details>
<summary>How do you deal with a situation where key stakeholders are not around and a big decision needs to be made? </summary><br><b>
</b></details>

<details>
<summary>Where do you see yourself 5 years down the line?</summary><br><b>
</b></details>

<details>
<summary>Give an example of a time when you were able to change the view of a team about a particular tool/project/technology</summary><br><b>
</b></details>

<details>
<summary>Have you ever caused a service outage? (or broke a working project, tool, ...?)</summary><br><b>

If you worked in this area for more than 5 years it's hard to imagine the answer would be no. It also doesn't have to be big service outage. Maybe you merged some code that broke a project or its tests. Simply focus on what you learned from such experience.
</b></details>

<details>
<summary>Rank the following in order 1 to 5, where 1 is most important: salaray, benefits, career, team/people, work life balance</summary><br><b>

You know best your order just have a good thought if you really want to put salary in top or bottom....

<details>
<summary>You have three important tasks scheduled for today. One is for your boss, second for a colleague who is also a friend, third is for a customer. All tasks are equally important. What do you do first?</summary><br><b>
</b></details>

<details>
<summary>You have a colleague you don‘t get along with. Tell us some strategies how you create a good work relationship with them anyway.</summary><br><b>

Bad answer: I don't.
Better answer: Every person has strengths and weaknesses. This is true also for colleagues I don't have good work relationship with and this is what helps me to create good work relationship with them. If I am able to highlight or recognize their strengths I'm able to focus mainly on that when communicating with them.
