Round 3: [Big Data specific coding (Spark)]

• Implement explode function (without using pre-built spark explode)
• Some questions about Spark

Round 4: [Behavioral]

Round 5: [Coding]

• Some easy sql questions.
• Given 2 Strings: Check if you can make the second string by copypasting the whole first string multiple times and inserting it in any place.

"XY" "XXXYYY" -> True (XY -> X[XY]Y -> XX[XY]YY)

Round 6: [Coding]

• Some Big Data specific questions (Spark)

• The problem i met first time:
  Given 2 things: array of tuple pairs(chars) and string. Check if you can make this string using characters in this tuples. The main requirement: if you used one element in tuple, you can not use the second element in the same tuple and vice versa

  [("l" , "e") , ("u" , "t"), ("c" , "o")] , "cul" -> True
  [("l" , "e") , ("u" , "t"), ("c" , "o")] , "lut" -> False
  [("l" , "e") , ("u" , "t"), ("c" , "o")] , "leco" -> False
