Interview process in Glovo is a very lengthy process. Mine took almost 2 months.
round1 : HR interview - basic questions on technology
round2 : Live coding round - 1.5 hrs on eclipse with JUnit enabled. check if list has cycle, find sequence of n elements in array that has the max sum, check if paranthesis string is valid or not
round3 : Tech Screen - 1.5 hrs : Microservices - what are they, when to use, what are to cons how do the services communicate with each other. RESTFull webservices - when & how to version, what documentation do you use, how will we deploy another version without having down time, give rest api endpoints for some ecample system, GET vs PUT vs POST http verbs. can put be used to do post work? can get be used to do post work. how is request body sent over the network, sending data in URL vs in request body - which is safe,circuit breaker, how to analyse performance/if service is failing for certain scenarios(similar to X-Ray service)
Java - what will be time complexity of storing a given value in HashMap.
DS & Algo - if 2 algo have same space & time complexity, will they take same time to execute
OS concepts - difference between threads & processes. can thread invoke a process, can process invoke a thread, how do 2 threads communicate, how do 2 processes communicate can 2 threads share same memory, can a process exist without any threads
sql vs noSql. when to use when,types of noSQL db,what is data sharding - how to select columns for data sharding
