The worst hiring process I have ever encountered. There was a complete disregard for the candidate's time and effort. It’s best not to waste your valuable time on an interview here, as they clearly don’t care about it.
I was invited for an initial HR chat for the Data Scientist position in Paris. After that I had an initial hiring manager call. Till then, my experience was positive. After that, the disaster starts to unfold. I was asked to complete a "Data Science" challenge and submit it within one week. Upon receiving the challenge, I asked a clarification about the task to the HR, which was never answered. Usually, companies provide clarification when requested, especially if you’re expected to spend a week on an assignment — this lack of response was a significant red flag. After submitting the assignment, I asked the HR to acknowledge its proper receipt. Again, no reply. If you go through the other negative reviews about this particular position in Glassdoor, you will see that the company ghosts candidates after they submit the assignments. So, I was quite sure that this was happening with me. But, I was mistaken. It turned out to be even worse!
Two weeks after submitting the assignment, I receive an email that the position was closed due to "internal structural changes". When, I asked the HR about why I was made to waste one week of my time when the company was itself not sure about the position, the HR very apologetically replied to me that there had been a mix up regarding a different position they were recruiting for and my profile ended up on a list where it shouldn't have been! Then he said that he confirmed with the team that the review was positive and he gave me two dates to choose from to appear for the next "onsite" task-review interview at their office. Then, I was given a description of what to expect in the task-review interview and I was told that the HR was working with the team to get some availability on their sides as the initial suggested dates were not available. I had almost forgiven them, but no, they had other tricks to pull up behind their sleeves! Three weeks after receiving the last message, when I approached them once more for an update, the HR tells me that after a second "deeper" review of my previous task they are not moving ahead with me. Also, they provided me with an unsatisfactory feedback (very superficial, does not align with the expectation of the task).
Overall, it was the most horrible interview experience for me. The repeated miscommunications and the lack of respect for the candidates is beyond comprehension. No candidate should be made to go through so much suffering for the utter lack of professionalism on their behalf.
