Do not waste your time; they will ghost you after all the rounds. HRs do not have the courtesy to inform you that you are not selected. On multiple follow-ups, they replied by saying, "We need an immediate joiner within 5 days." The irony is they themselves took a month to complete the whole process, but they want people to join in the blink of an eye. The process is lengthy. I gave 5 rounds:

• 1 technical
• 1 techno-managerial
• 2 director rounds
• 1 HR

Technical:

• What are the Java 8 features?
• How to handle out of memory?
• What do you check in a code review?
• What test tools are used for monitoring code coverage?
• Can you write PL/SQL?
• How do you handle a DB sequence?
• Commands used in Dockerfile?
• Binary search implementation.
• Any caches have you used?
• Angular apply vs. callback function.
• Write code using Executor Service.

Code: Remove all trailing zeros from mid and append in last.

Other rounds: Mostly behavioral questions.
