Question 1
(2) 3Sum of inequality relationship: return number of triples
(3) uncompress run length based sequences from multiple channels, then compress again, each sequence has sequence number from each channel, the sequence number can mess up a little (< 10 between true position and received position)

Was scheduled two rounds of online live coding sessions. Problems were average, and solved both in given time. Interviewers' response was generally positive. Though one interviewer was more supportive than the other. Was told not to proceed further without any explanation.
