I just got done with Salesforce Hackerrank OA. The test has two questions. I'd say the first one was kinda okay but the second one was freaking hard for sure .

Q1.

Q2:

PS:

I solved the first one completely.
I solved the second one with DFS but I was only able to pass 11 out 15 test cases .
Tip: Use BFS or Union Find

Q2: https://leetcode.com/problems/minimize-malware-spread/description

Funny thing was , I saw this question yesterday and It thought of solving it but I didn't . And I showed up today.

Good Luck everyone :)

Input
The first line of input consists of two space separated integers n
(1≤n≤105)
and m
(1≤m≤105)
. The next m lines each consist of 2 space separated integers, u and v, which denote that there is an edge between the nodes u and v
.

Output
The output consists of a single integer - the maximum difference across all connected components.

We talked about SPA, Performance , Optimization, Testing and common questions like have you ever had a conflict type things . He also asked scenario based question like what if your site etc.

Lastly the guy talked about Salesforce work culture and how it operates and different that other companies . I asked him a couple of questions and we concluded.
