I applied via LinkedIn and HR called within 2 days 1st round was telephonic round. Asked about Linux,shell scripting,docker,chef,git etc. 2nd was f2f at Oracle Bangalore location. Asked again more about Linux, scripting, automation, configuration management etc 3rd was managerial . More into roles and salary discussion. Whole process took 3weeks of time to get the official offer which was pretty fast I feel.
