I applied online. I interviewed at Cohesity (Bengaluru) in Sept 2017
Interview
Well in one word if I have to describe the company interview process then I would say long, frustrating and unprofessional.
Even in India company doesn't have HR office receptionist handles the same responsibility so don't expect HR professionalism.
It took 1 month for all interviews, I have told them I am already on notice period please speed up the process for letting me know the interview feedback and results but as usual they took one week for one interview feedback, I don't understand what is the logic behind make the candidate waiting for result.
Process: 1 Round on 14 Sep almost 1:15 hours long. Interviewer was very nice person asked questions on Virtualization, Testing, Linux, Storage, Coding (string,list manipulation ).
Got feedback after multiple emails and call that she is going to schedule one more round.
2nd round : Again telephonic as I am on another state, duration 30 min. asked same question as first one.
Simple coding on Colabedit.
Round 3-8
Now they scheduled back to back 6 rounds each round of 1 hours
In short all have asked same questions nothing new. Company needs to review their panelist questions or should be sync.
Everyone asked to coding in colabedit link.
1. Simple programs of dictionary, occurrence of letter in word,
2. find second largest,
3. find the unmatched pattern in file.
4. Compare two large file. (Binary search)
5. Find valid IP in log file
6. Find specific pattern in logfile
7. Maximum length of consecutive number in list.
8. Merge two sorted list
(Thanks me for this :))
Favourite ques. debugging of network down.
One of the panelist asked me to show the face on zoom and as he was shy he didn't bother to start his video. mentioned this because among all he was quite rude and had no idea what he was asking, He was very poor in coding and I had to struggle a lot to explain him my code and logic. That thing also gave me an idea that I am thinking too much about this company but interviewer also reflect the company culture and working style.
And again after one week after following up I got the automated rejection email :(
I applied through university. I interviewed at Cohesity (Bengaluru) in Dec 2023
Interview
They asked a hard leet code question on graph.
My panel asked a hard question
But for other panels questions are rather easy and are on array string topics overall interview is medium to hard fore me.

Scenario
You are part of the Spam Prevention Team for a microblogging service. You noticed that many accounts only retweet other tweets, instead of creating original content. These accounts usually belong to spammers, and your task is to build a program that detects them.
You have access to platform's activity log (available at /home/candidate/candidate_files/java/inputs). The structure of the activity log is described in /home/candidate/candidate_files/java/log_structure.txt.
We consider a user to be a spammer if he satisfies all the following criteria:
The user has no original tweets.
The user has at least one retweet.
All the retweets of this user occur within 1000 milliseconds of the original tweet.
Task
Write the function identify_spammers that accepts the absolute path of the activity logfile, and returns a list of all the spammer usernames. For example,
[
"pkoch",
"MagnusCarlsen",
...
]
