      Solicitud

      Solicité el puesto a través de un captador. El proceso duró 1 día. Acudí a una entrevista en Prowareness (Bengaluru) en mar 2017

      Entrevista

      1 Got Call for Interview for next day. 2. Technical Discussion . Panel seemed to have fixed question of Spark, Hive and SQL Questions were mostly difference two things . Few specific single word answer questions (One answer interviewer had in mind). The approach to answer would be stopped in between and asked to answer specific question. I found few questions very negative and boundary condition or anomaly type or interviewer wanted to answer in his word only like two primary-key possible ?, which file format spark saves job ? sorting of indexing ? Approach to solution was not appreciated or stopped then and there. I gave string feedback to HR about panel. No question on map-reduce or java or spark-dataframe . Answer to my role and responsibility : Teach and up-skill the team( us and others ) on big-data.

      Preguntas de entrevista [1]

      Pregunta 1

      Spark : 1. Difference between map and flatmap. 2. Difference between groupbykey and reducebykey 3. Which file format spark saves file ? Answer should be ".orc" files only. (It took me multiple attempts to understand the question. and ".txt", ".csv" "xml" "anyflat-file-format" is not the correct answer. LOL ) 4. Difference between coalesce and repartition. 5. some more questions on RDD Hive 1 Difference between orderby and sortby 2. Select * from . How many mapper will be created. 3. Analytical function/ What is RANK ? hdfs 1. Difference between block and split SQL 1. What is indexing on single column ? (stopped in between of my answer ) and followed by what is sorting type in index key ascending or descending. (How does it matter its primary key not composite key) 2. Can you have two primary key . (I do not thing there will need of two primary as one it self does the job.) No tell the implementation is it possible, can you define two primary key ? (No) One of the panel member got irritated and fired a few questions after saying bye and answering my question related to profile and position . (Literally like Panel one : okay bye thanks for you ... Panel: No I will ask one last question . which file format spark saves files. )
