I applied online. The process took 1 day. I interviewed at Postman (Bengaluru) in Oct 2020
Interview
The interviewer were friendly. But, the interview process is designed to ask question which interviewer seems to be important which is highly dependent on interviewer's skill which is not suitable for Full Stack developer.
They want to imitate bar raise like Amazon but fail to ask question beyond elementary level which interviewer is familiar with.
But the interview focused only on monolith system design, basic MVC API design and some elementary level questions which was not I was hoping for.
Since, most of the key areas of full stack development like System Design, CI/CD, Cloud Technology & security, Streaming analytics, Micro Service Mesh architecture, etc were never asked.
Interview questions [5]
Question 1
As a full stack developer, I attended two rounds of interview:
First round:
- Find a duplicate in Array:
-- For unsorted: explained using set
-- For sorted: Explained using Total sum
-- For O(1) space: explained using Bloom Filter
First round:
- How encryption works in HTTPS? Interviewer not aware of CyperSuite concepts and just focuses on initial asymmetric key sharing phase. As expected from young people asking questions, since cypersuite was never explained in College i guess.
Second Round:
- API design for displaying user activities
-- Used Nest.js to design MVC.
-- Simple Heartbeat solution to update timestamps over WebScoket and to retrive latest online user and plot history of user activity over RDB.
-- Suggested to use Key value store like Redis to improve latency.
-- Finally a single good question worth of interview:
---- Discussed about scaling by using consistent hashing over document_id to distribute load over multiple datastore and use LB over containers

Aptitude and tech interview round. Aptitude was easy with simple questions. The tech interview focussed on my ability in react and next. The interviewer seemed to be the most intelligent guy I have ever seen,even though he was a front end developer he had knowledge about bi-lstm neural network, which blew my mind.
