LinkedIn IOS Engineer interview questions

Got a message from the recruiter on linkedIn that my profile has matched the JD and would like to setup a call. A brief 15 min call with the recruiter. Then it was a 1 hour technical screening. In the screening the developer asked 8-10 iOS hitters and then we dived into coding. Basic BFS and DFS question which we wrapped up in like 20-25 minutes. Then we just chatted and ended the interview. Later the HR told me that LinkedIn s interview will be onsite for the super day and I d need to fly to Mountain View HQ for that. I was eager for that and waited for the next step. After that the HRs just disappeared. I emailed and messaged her on LinkedIn but no luck. Extremely disappointed.
