Fragen im Vorstellungsgespräch: Consultant in Dublin, Irland

I didn't know it but he said it's CURL and WGET

ssh

You would SSH in, you would also require the IP address of the server and likely a key pair for authentication

I was quite bad at this since i haven't worked with servers that much. I said 8888 for http and said i don't know the port for https. But after the interview I googled it and looks like it's 80 for http and 443 for https. So it was a lesson learned.

http: 80 https : 443

I said i usually use google analytics to see my users' behavior but i do know that IP address is used to know information about the users, like where they are connected from and so on. But i am not sure how i can determine the type of their devices. He told me the asnwer is http header.

HTTP header : User-Agent header is the exact answer to identify the device

Implement a way of iterating through an array of integers and returning only duplicate values within the array, wasn't able to answer this one but did give me a hint abut using hashmaps to do it

import java.util.*; public class GetDuplicates { public static void main(String args[]){ // get input Scanner sc = new Scanner(System.in); ArrayList nums = new ArrayList(); while(sc.hasNext()) { String num = sc.next().trim(); if (num.equals("q")) break; nums.add(Integer.parseInt(num)); } Set set = new HashSet(); for(int n : nums) { if(set.contains(n)) { System.out.print(n + " "); } else { set.add(n); } } } }

You can google test src itself by archive name, however not the answers. Just in case if that could help someone.

How can you google it? what name of the test do you use?

I said that it's important not to pressure the client on buying right away, and instead allowing them time to think of their best options, while also offering to follow up on their interest and see if they have made a decision by the next time you reach out to them.

It's alright, you can take your time. But I assure you that we'll give you the exact quality of what you really want. Thank you

blah blah blah.

Did you ever get a reply from IBM? Thanks.
