A recruiter mailed me informing me of a job opportunity. After registering on the company website, I was sent a HackerRank test, which I cleared. The next day, I received an email from the recruiter stating that the tech interview would be the following day. I waited all day for an email with more information, but none was sent. Later, I received an email to complete a cognitive ability test. The next day, an HR representative contacted me to schedule the tech interview and asked for my availability. I suggested 3 PM. They sent a link for 4 PM but canceled it without informing me and rescheduled it for the next day at 10:30 AM. Another HR representative contacted me, stating the interview would be at 4 PM and to ignore the previous email. Later, both interviews were canceled.

I have no idea why they wasted my time. I spent almost four to five days on this, a complete waste of time.

Two Java programs are given in the HackerRank test.
