The process began with a call with HR, followed by an easy interview with a developer. Subsequently, I was invited to a virtual onsite, which was broken into five interviews over three days.

I was informed that if I failed any of the days, I would not proceed to the next.

On the second day, I logged into the meeting, but no one was present. After waiting for 15 minutes, I contacted HR, and they responded: "Oh, yes, you didn't make it to the next round. I just forgot to tell you, sorry."

I have failed interviews before, but this was by far the most humiliating way I was informed. I was honestly shocked.

All of the interviewers were nice and professional. However, I did have some difficulty understanding their accents. I am Russian, and I assume all of them were Indian.

Additionally, Bloomberg was hiring for a specific position, not for the company in general, which always reduces the chances of being hired.

Q: You have two methods: update a hashtag (can be slow) and return the top K hashtags (must be fast). How would you implement them?

Q: You have two words and a dictionary. You must transform the first word to the second by changing one letter at a time. What is the minimum number of steps in which you can get to the second word? All of the words in the steps must be from the dictionary.
