I applied through a recruiter. The process took 1 day. I interviewed at Couchbase (Bengaluru) in Feb 2018
Interview
It was told to be one/two skype screening and then onsite 5-6 rounds (whole day) at their koramangala office.
In the telephonic round, he asked me 1 programming question i.e. merging of intervals. And some design questions on factory design pattern. He also said that he had another programming question which he could not ask due to shortage of time. IMO, it is almost impossible to implement best solutions for 2 questions in 1 hr skype call.
It was a skype call and then he shared a google document and asked me to write code on it. I did answer them all correctly but still they dropped my candidature which is kind of strange though!
And also, it looked to me that the interviewer is a junior engineer who did not have much experience in conducting interviews.
Overall it was total disappointment for me.
Interview questions [1]
Question 1
1. merge given intervals e.g. {1, 9}, {2, 3}, {5, 10} -->{1, 3}, {5, 10}
Ans. Sort the list by 'x' values. Then scan each of them and merge. Complexity O(nlogn).
2. A design question which can be solved using factory method, prototype, flyweight.
Phone screen with recruiter followed by a virtual on-site of about six technical interviews done over Zoom. Not much behavioral questions. Most of the tech interviews were derived from problems related to the job opening. One of these was a larger-scale design and coding effort that lasted longer. One was easy to medium Leetcode type questions. Coding done on Google Docs so no compilation.

Question 1
Design and implement some APIs for an efficient way to store and retrieve data in memory, including for range scans.
I applied through an employee referral. The process took 3 weeks. I interviewed at Couchbase in Jan 2022
Interview
Was told 5 rounds in total. All rounds are elimination
was eliminated at this stage. felt round1 was a negative. did not get feedback from the recruiter. just a generic rejection email.
Interview questions [1]
Question 1
round1: concurrency/multithreading (given a large file, perform operations in parallel on each line within that file) think producer-consumer type problem
round2: ds/algo. lc medium/easy
I applied online. I interviewed at Couchbase (Bengaluru) in Nov 2021
Interview
Interviewed for eventing team.
Two online interviews.
Easy data structure questions.
I came across incompetent interviewer during interviews .I think couch base should raise bar of their interviewers.
For me it was waste of time.
