got a job offer but said no interview was needed??

been searching for a job for months and i finally got an offer from a renovation company, only thing is they said no interview was needed? the email stated it would be conducted after a "30 day trial" period then 60 days probationary period. this is a bit odd to me. i've never had a job offer that didnt do an interview. the company then sent a email wanting me to sign up for an app they use their payroll on. is this normal when working in residential construction?

EDIT: i responded back to them clarifying i'd feel more comfortable meeting in person before accepting the offer to discuss responsibilities, pay, schedule etc. and somehow got an interview in person on Tuesday. Also said 30 day trial would be paid, fingers crossed it's a good job.
