How do you know how much memory your java application is taking on Linux?

pmap or top is probably the simplest. Just be sure not to confuse virtual memory with physical. Moins

I tried solving it with python I gave some solution it didn't worked well.

public class Column { static int getColumnPosition(String cell) { int columnposition = 1; int row = 0; int j = 0; char[] cellAsArray = cell.toCharArray(); char column = cellAsArray[cellAsArray.length - 1]; for (int i=0; i = 'A' && letter <= 'Z') { letterPosition += 1 + letter - 'A'; } return letterPosition; } public static void main(String[] args) { int position = getColumnPosition("ZZ"); System.out.println("Position is " +position); } } Moins

num = 0 for char in list('AZA'): num = num + ord(char) - ord('A') + 1 return num Moins

How do you stay organized? Describe tools and techniques.

3 réponses

I use Outlook for email, contacts, calendar, and tasks in the work environment, and I use OneNote to collect and search through important notes. With my smartphone I use Google's calendar, gmail, and search. Moins

Trello for managing/limiting work in progress; focusing on one task at a time. Don't use email at all if you can help it. Use Slack for team communication as it links with Trello effectively. Keep all of your code in GitHub and commit+push often to track changes. Don't be someone responsible for releasing software; be someone who enables teams to release via services or automation you provide. Work hard to keep from being a bottleneck or gatekeeper of environments. Don't keep secrets or build silos of knowledge. The mindset you adopt will enable you to uplift others and enable better communication across your team and organization. Moins

Choose carefully what you put your attention on and resist the urge to multitask. Choose your top 2 or 3 skill areas and focus on cultivating them. Tools like Outlook are not helpful for DevOps. Shut it off for long periods of time each day. Moins

I was asked to to participate in several thought experiments. They were cleverly designed for you to showcase your skillset.

2 réponses

I really just provided honest input during the thought experiments, and this demonstrated my proficiency with the concepts and software involved in the thought experiments. Moins

Through questions like this, interviewers are mostly trying to test your skillset (and its relevance to the role) as robustly as possible, so be prepared for multiple offshoots and followups. It could be a useful exercise to do mocks with friends or colleagues in Imgur to get a real sense of what the interview is actually like. Alternatively Prepfully has a ton of Imgur Senior DevOps Engineer experts who provide mock interviews for a pretty reasonable amount. prepfully.com/practice-interviews Moins

If you could have one superpower...

2 réponses

Be clever when responding. Whether it's the ability to fly, see into the future or leap over tall buildings in a single bound, you should always make a connection to your professional contributions. The superpower you choose need to relate back to an organization or how your skills would benefit others. For example, the ability to read someone's mind can help you create better solutions for a client. Moins

Meh. These questions always freak me out a little bit. I don't think it was considered seriously, instead looking for someone with a little bit of life in them. Typical programmer trap though - flying is a subset of teleportation :P Moins

How would you design a presence (ie: friends online list) system?

2 réponses

K/V stores, queues, distributed systems, etc etc. If you don't have an opinion on this, you haven't been on-call for a chat system before :P Moins

In these sorts of interviews you really need to drill down and understand what the interviewer is looking for. A good way to simulate a real interview experience is to do a mock with one of the Imgur Devops Engineer experts on Prepfully, rated super strongly on TrustPilot... prepfully.com/practice-interviews Moins

Are you a consultant?

2 réponses

I stared at him a bit then finished my coffee and left.

Sorry, but I think you got this question wrong in your interview. If you are interviewing for a consulting position, the answer to this is “yes.” If you are interviewing for a full time position, the answer to this is “no.” Moins
