As others have mentioned, this company performs company espionage.

The interview process includes:

• A recruiter phone screen.
• A HackerRank assessment (I received a very easy stack interpreter with instructions such as push, print, add, etc.).
• A standard technical phone screen.
• A full-day onsite where they present their products for hours, followed by three hour-long back-to-back interviews (two coding, one design) with no breaks.

Even though they advertise the role as "new grad," they are not looking to hire new grads at all. I solved all problems within their timeframe and did not receive an offer or constructive feedback other than the fact that they have a "high bar."

Be prepared to be constantly berated with questions like, "How's your interview schedule doing?", "Which companies are you applying to/currently interviewing with?", and "Do you have any other offers?"

Don't be deceived by the recruiter's offer to "let me help you prepare for your interview; let's set up a time to talk." This is merely an opportunity for them to pry into your interview schedule, etc.

The only perk is the free hotel accommodation.

Even though they list the position as "Software Engineer (New Grad)," they are not really looking for new grads. Shady recruiters.
