Google SWE Intern interview questions

I applied for software engineer Intern at google for 2020 they sent me a mail to schedule slots for 2 interviews back-to-back each one was 45 mins Problem solving only and after the 2 interviews they asked me to do one extra interview

Went through online online challenge. For emea region, the questions were equivalent to leetcode easy. Was given 2 problems on 90 minutes. After the challenge was scheduled for 2 back to back phone interviews
