Sproxil interview questions

A google meet call, interacted with a developer and HR. solved algorithm and was given home assessment. I don't have any other word to add to this. why will a platform be useless regarding specifications of minimum content they want the user to enter?

​​" Fraud Company " - I have cleared all the interview rounds and received mail from HR as well. After submitting the docs, HR said they will release the offer letter 1 month before joining ,then they started delaying that, and before 25 days of joining they said they will release the offer before 15 days. All this conversation they were doing on call. so many times I asked to send some confirmation mail for job surety but they didn't. After ​my ​all the reminder mail ​, ​HR called me and said 'Don't worry, your job is secure, etc' but Now it's my last working Week in my current org and before 2 weeks of joining they are not responding to any mails and calls.
