Thumbtack Ios Software Engineer interview questions

I applied on its website. The whole process took about a month. I interview at thumbtack HQ at SF in June 2017. I was first contacted by a recruiter then had a phone chat with him. Then I was schedule to have a chat with a iOS developer. It was not a technical interview. We just talked about my pass projects and the role and the company. Then a technical phone interview was scheduled. It was not very hard. A dictionary related question. The on-site interviews contained 3 general algorithm interviews & 1 iOS coding. The last one was to implement a feature base on their code base. All the interviews were nice.
