Unfortunately, I can't advise anyone to join them. The management behaved very unprofessionally with me, and many other cases sounded very similar to mine. I came to Fios Genomics from abroad, and after 4 (!) interviews, remote and in person, in which we definitely had the possibility to appreciate each other both technically and personally, I have been asked by them to trust and join the company. It was a difficult decision for me, but in the end, I considered it a good opportunity for my career and accepted. I left a very good piece of work at Fios, and a lot more needed to be done. Their technical setup and the quality of the code that I found were certainly poor according to my professional standard (but possibly also according to any common one), but that was OK: I had a high-level technical role and lived it as a challenge. Of course, it took me a couple of months to get specifically into the topic, but nobody with common good sense could have expected the contrary, especially having well in mind to have asked for a relocation from a different country. Unfortunately, only a couple of months after joining, they clearly showed to have already changed their mind, and after few more months, I have been taken apart with the excuse of a meeting and never allowed to come back to the office, not even for a greeting to my ex-colleagues. No other relevant communications or explanations. Just the usual excuses. I was very dedicated during my work there, but I was treated pretty much as if I were a thief.
They demonstrated a lack of a sense of responsibility for what ultimately was their initiative, let alone empathy.
