I applied through a staffing agency. The process took 1 day. I interviewed at IBM (Calcutta) in Sept 2019
Interview
I went at IBM office in KOLKATA at DLF 1. First there was a online assesment for Microservices - Spring Boot. After clearing the assessment I was called in for the 1st round of interview which was Technical and was taken over phone on the same day. Then after 1 hour I was called in for the 2nd round of interview which was basically Managerial + HR. The interview asked me questions like "Describe your current project architecture." "What is the most difficult phase you faced in your current organization and how did you handle it?".
After the 2nd round I waited for half an hour and then I was called in for biometrics. The IBM personnel took my photo, finger prints, documents.
One week later I got the offer letter.
Interview questions [1]
Question 1

What are Enums? Why should we use ENums? Do you know any caching framework like Redis? What is CICD process? What is pipeline? Jenkins, GIT,etc.
For me, there were two rounds of technical questions and one HR round. Each round is an elimination round. Usually the process completes within a couple of weeks. You might need to be patient though, and wait for them to roll out your offer.
