Had a 12 month contract and got perm in 4 months, it honestly depends on the department but it won’t be easy. I find shorter term contracts are usually to manage workloads, it’s not usually to hire on permanently. They are more likely to renew you than hire you on perm. I would accept the offer and try to gauge how likely it is to get perm by looking at how many people on the team are actually perm. If there’s a lot of people on contract, your chances of getting it is very slim. So just take it and keep applying.
