Absolutely ridiculous.
Solved an online Hackerrank, upon my application. Had a brief discussion with HR about benefits, including general non-technical questions, and arranged a technical one for the next stage. Had a difference of 1 hour with one of the possible locations of the interviewers and 7 hours with the other location, and she mentioned that it is actually of not-that-much-of-a-difference with whom I am taking it, so eventually I took the interview late evening.
The interview consisted of another hackerrank challenge along with some technical questions. Solved the challenge -despite, after describing my thought process to the interviewer, I was asked to re-do it, which stopped my thought process- to its full extend (deploy a simple function in the beginning, then a more complex one etc.) and tackled all of the questions.
Followed up twice or thrice, and received the typical rejection letter. Asked for feedback, as I was unable to understand what went wrong (they had told me that they are willing to cover my visa due to brexit - so that shouldn't be it) and received an answer that would be a great indicator of what the company is all about - a.k.a a red flag - something along the lines: "we cannot provide individual feedback". To me this sounds more like you cannot even provide feedback because you cannot even tell what went wrong.
The email also suggested implicitly lack of experience (entry level job) in addition to lack of enthusiasm and motivation (I was more excited than my interviewer along the process - was barely able to hear what they were saying).
Please stay away from companies that think that by simply creating an interview process like Google, they can get to the level of Google.
You have to do so much more work to get to that level and you have to start from within.
